[01:20:27] {"message":"cannot move out of borrowed content","code":{"code":"E0507","explanation":"\nYou tried to move out of a value which was borrowed. Erroneous code example:\n\n```compile_fail,E0507\nuse std::cell::RefCell;\n\nstruct TheDarkKnight;\n\nimpl TheDarkKnight {\n    fn nothing_is_true(self) {}\n}\n\nfn main() {\n    let x = RefCell::new(TheDarkKnight);\n\n    x.borrow().nothing_is_true(); // error: cannot move out of borrowed content\n}\n```\n\nHere, the `nothing_is_true` method takes the ownership of `self`. However,\n`self` cannot be moved because `.borrow()` only provides an `&TheDarkKnight`,\nwhich is a borrow of the content owned by the `RefCell`. To fix this error,\nyou have three choices:\n\n* Try to avoid moving the variable.\n* Somehow reclaim the ownership.\n* Implement the `Copy` trait on the type.\n\nExamples:\n\n```\nuse std::cell::RefCell;\n\nstruct TheDarkKnight;\n\nimpl TheDarkKnight {\n    fn nothing_is_true(&self) {} // First case, we don't take ownership\n}\n\nfn main() {\n    let x = RefCell::new(TheDarkKnight);\n\n    x.borrow().nothing_is_true(); // ok!\n}\n```\n\nOr:\n\n```\nuse std::cell::RefCell;\n\nstruct TheDarkKnight;\n\nimpl TheDarkKnight {\n    fn nothing_is_true(self) {}\n}\n\nfn main() {\n    let x = RefCell::new(TheDarkKnight);\n    let x = x.into_inner(); // we get back ownership\n\n    x.nothing_is_true(); // ok!\n}\n```\n\nOr:\n\n```\nuse std::cell::RefCell;\n\n#[derive(Clone, Copy)] // we implement the Copy trait\nstruct TheDarkKnight;\n\nimpl TheDarkKnight {\n    fn nothing_is_true(self) {}\n}\n\nfn main() {\n    let x = RefCell::new(TheDarkKnight);\n\n    x.borrow().nothing_is_true(); // ok!\n}\n```\n\nMoving a member out of a mutably borrowed struct will also cause E0507 error:\n\n```compile_fail,E0507\nstruct TheDarkKnight;\n\nimpl TheDarkKnight {\n    fn nothing_is_true(self) {}\n}\n\nstruct Batcave {\n    knight: TheDarkKnight\n}\n\nfn main() {\n    let mut cave = Batcave {\n        knight: TheDarkKnight\n    };\n    let borrowed = &mut cave;\n\n    borrowed.knight.nothing_is_true(); // E0507\n}\n```\n\nIt is fine only if you put something back. `mem::replace` can be used for that:\n\n```\n# struct TheDarkKnight;\n# impl TheDarkKnight { fn nothing_is_true(self) {} }\n# struct Batcave { knight: TheDarkKnight }\nuse std::mem;\n\nlet mut cave = Batcave {\n    knight: TheDarkKnight\n};\nlet borrowed = &mut cave;\n\nmem::replace(&mut borrowed.knight, TheDarkKnight).nothing_is_true(); // ok!\n```\n\nYou can find more information about borrowing in the rust-book:\nhttp://doc.rust-lang.org/book/first-edition/references-and-borrowing.html\n"},"level":"error","spans":[{"file_name":"/checkout/src/test/ui/access-mode-in-closures.rs","byte_start":647,"byte_end":649,"line_start":18,"line_end":18,"column_start":15,"column_end":17,"is_primary":true,"text":[{"text":"        match *s { S(v) => v } //~ ERROR cannot move out","highlight_start":15,"highlight_end":17}],"label":"cannot move out of borrowed content","suggested_replacement":null,"suggestion_applicability":null,"expansion":null},{"file_name":"/checkout/src/test/ui/access-mode-in-closures.rs","byte_start":654,"byte_end":655,"line_start":18,"line_end":18,"column_start":22,"column_end":23,"is_primary":false,"text":[{"text":"        match *s { S(v) => v } //~ ERROR cannot move out","highlight_start":22,"highlight_end":23}],"label":"data moved here","suggested_replacement":null,"suggestion_applicability":null,"expansion":null}],"children":[{"message":"move occurs because `v` has type `std::vec::Vec<isize>`, which does not implement the `Copy` trait","code":null,"level":"note","spans":[{"file_name":"/checkout/src/test/ui/access-mode-in-closures.rs","byte_start":654,"byte_end":655,"line_start":18,"line_end":18,"column_start":22,"column_end":23,"is_primary":true,"text":[{"text":"        match *s { S(v) => v } //~ ERROR cannot move out","highlight_start":22,"highlight_end":23}],"label":null,"suggested_replacement":null,"suggestion_applicability":null,"expansion":null}],"children":[],"rendered":null},{"message":"consider removing the `*`","code":null,"level":"help","spans":[{"file_name":"/checkout/src/test/ui/access-mode-in-closures.rs","byte_start":647,"byte_end":649,"line_start":18,"line_end":18,"column_start":15,"column_end":17,"is_primary":true,"text":[{"text":"        match *s { S(v) => v } //~ ERROR cannot move out","highlight_start":15,"highlight_end":17}],"label":null,"suggested_replacement":"s","suggestion_applicability":"Unspecified","expansion":null}],"children":[],"rendered":null}],"rendered":"error[E0507]: cannot move out of borrowed content\n  --> /checkout/src/test/ui/access-mode-in-closures.rs:18:15\n   |\nLL |         match *s { S(v) => v } //~ ERROR cannot move out\n   |               ^^     - data moved here\n   |               |\n   |               cannot move out of borrowed content\n   |               help: consider removing the `*`: `s`\n   |\nnote: move occurs because `v` has type `std::vec::Vec<isize>`, which does not implement the `Copy` trait\n  --> /checkout/src/test/ui/access-mode-in-closures.rs:18:22\n   |\nLL |         match *s { S(v) => v } //~ ERROR cannot move out\n   |                      ^\n\n"}

[01:20:27] {"message":"temporary value dropped while borrowed","code":{"code":"E0716","explanation":"\nThis error indicates that a temporary value is being dropped\nwhile a borrow is still in active use.\n\nErroneous code example:\n\n```compile_fail,E0716\n# #![feature(nll)]\nfn foo() -> i32 { 22 }\nfn bar(x: &i32) -> &i32 { x }\nlet p = bar(&foo());\n         // ------ creates a temporary\nlet q = *p;\n```\n\nHere, the expression `&foo()` is borrowing the expression\n`foo()`. As `foo()` is call to a function, and not the name of\na variable, this creates a **temporary** -- that temporary stores\nthe return value from `foo()` so that it can be borrowed.\nSo you might imagine that `let p = bar(&foo())` is equivalent\nto this:\n\n```compile_fail,E0597\n# fn foo() -> i32 { 22 }\n# fn bar(x: &i32) -> &i32 { x }\nlet p = {\n  let tmp = foo(); // the temporary\n  bar(&tmp)\n}; // <-- tmp is freed as we exit this block\nlet q = p;\n```\n\nWhenever a temporary is created, it is automatically dropped (freed)\naccording to fixed rules. Ordinarily, the temporary is dropped\nat the end of the enclosing statement -- in this case, after the `let`.\nThis is illustrated in the example above by showing that `tmp` would\nbe freed as we exit the block.\n\nTo fix this problem, you need to create a local variable\nto store the value in rather than relying on a temporary.\nFor example, you might change the original program to\nthe following:\n\n```\nfn foo() -> i32 { 22 }\nfn bar(x: &i32) -> &i32 { x }\nlet value = foo(); // dropped at the end of the enclosing block\nlet p = bar(&value);\nlet q = *p;\n```\n\nBy introducing the explicit `let value`, we allocate storage\nthat will last until the end of the enclosing block (when `value`\ngoes out of scope). When we borrow `&value`, we are borrowing a\nlocal variable that already exists, and hence no temporary is created.\n\nTemporaries are not always dropped at the end of the enclosing\nstatement. In simple cases where the `&` expression is immediately\nstored into a variable, the compiler will automatically extend\nthe lifetime of the temporary until the end of the enclosinb\nblock. Therefore, an alternative way to fix the original\nprogram is to write `let tmp = &foo()` and not `let tmp = foo()`:\n\n```\nfn foo() -> i32 { 22 }\nfn bar(x: &i32) -> &i32 { x }\nlet value = &foo();\nlet p = bar(value);\nlet q = *p;\n```\n\nHere, we are still borrowing `foo()`, but as the borrow is assigned\ndirectly into a variable, the temporary will not be dropped until\nthe end of the enclosing block. Similar rules apply when temporaries\nare stored into aggregate structures like a tuple or struct:\n\n```\n// Here, two temporaries are created, but\n// as they are stored directly into `value`,\n// they are not dropped until the end of the\n// enclosing block.\nfn foo() -> i32 { 22 }\nlet value = (&foo(), &foo());\n```\n"},"level":"error","spans":[{"file_name":"<::alloc::macros::vec macros>","byte_start":115,"byte_end":162,"line_start":3,"line_end":3,"column_start":1,"column_end":48,"is_primary":true,"text":[{"text":"< [ _ ] > :: into_vec ( box [ $ ( $ x ) , * ] ) ) ; ( $ ( $ x : expr , ) * )","highlight_start":1,"highlight_end":48}],"label":"creates a temporary which is freed while still in use","suggested_replacement":null,"suggestion_applicability":null,"expansion":{"span":{"file_name":"/checkout/src/test/ui/borrowck/borrowck-borrowed-uniq-rvalue-2.rs","byte_start":751,"byte_end":776,"line_start":30,"line_end":30,"column_start":20,"column_end":45,"is_primary":false,"text":[{"text":"    let x = defer(&vec![\"Goodbye\", \"world!\"]); //~ ERROR borrowed value does not live long enough","highlight_start":20,"highlight_end":45}],"label":null,"suggested_replacement":null,"suggestion_applicability":null,"expansion":null},"macro_decl_name":"vec!","def_site_span":{"file_name":"<::alloc::macros::vec macros>","byte_start":0,"byte_end":222,"line_start":1,"line_end":4,"column_start":1,"column_end":31,"is_primary":false,"text":[{"text":"( $ elem : expr ; $ n : expr ) => (","highlight_start":1,"highlight_end":36},{"text":"$ crate :: vec :: from_elem ( $ elem , $ n ) ) ; ( $ ( $ x : expr ) , * ) => (","highlight_start":1,"highlight_end":79},{"text":"< [ _ ] > :: into_vec ( box [ $ ( $ x ) , * ] ) ) ; ( $ ( $ x : expr , ) * )","highlight_start":1,"highlight_end":77},{"text":"=> ( vec !

[01:20:27] {"message":"borrow of moved value: `x`","code":{"code":"E0382","explanation":"\nThis error occurs when an attempt is made to use a variable after its contents\nhave been moved elsewhere. For example:\n\n```compile_fail,E0382\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = MyStruct{ s: 5u32 };\n    let y = x;\n    x.s = 6;\n    println!(\"{}\", x.s);\n}\n```\n\nSince `MyStruct` is a type that is not marked `Copy`, the data gets moved out\nof `x` when we set `y`. This is fundamental to Rust's ownership system: outside\nof workarounds like `Rc`, a value cannot be owned by more than one variable.\n\nSometimes we don't need to move the value. Using a reference, we can let another\nfunction borrow the value without changing its ownership. In the example below,\nwe don't actually have to move our string to `calculate_length`, we can give it\na reference to it with `&` instead.\n\n```\nfn main() {\n    let s1 = String::from(\"hello\");\n\n    let len = calculate_length(&s1);\n\n    println!(\"The length of '{}' is {}.\", s1, len);\n}\n\nfn calculate_length(s: &String) -> usize {\n    s.len()\n}\n```\n\nA mutable reference can be created with `&mut`.\n\nSometimes we don't want a reference, but a duplicate. All types marked `Clone`\ncan be duplicated by calling `.clone()`. Subsequent changes to a clone do not\naffect the original variable.\n\nMost types in the standard library are marked `Clone`. The example below\ndemonstrates using `clone()` on a string. `s1` is first set to \"many\", and then\ncopied to `s2`. Then the first character of `s1` is removed, without affecting\n`s2`. \"any many\" is printed to the console.\n\n```\nfn main() {\n    let mut s1 = String::from(\"many\");\n    let s2 = s1.clone();\n    s1.remove(0);\n    println!(\"{} {}\", s1, s2);\n}\n```\n\nIf we control the definition of a type, we can implement `Clone` on it ourselves\nwith `#[derive(Clone)]`.\n\nSome types have no ownership semantics at all and are trivial to duplicate. An\nexample is `i32` and the other number types. We don't have to call `.clone()` to\nclone them, because they are marked `Copy` in addition to `Clone`.  Implicit\ncloning is more convenient in this case. We can mark our own types `Copy` if\nall their members also are marked `Copy`.\n\nIn the example below, we implement a `Point` type. Because it only stores two\nintegers, we opt-out of ownership semantics with `Copy`. Then we can\n`let p2 = p1` without `p1` being moved.\n\n```\n#[derive(Copy, Clone)]\nstruct Point { x: i32, y: i32 }\n\nfn main() {\n    let mut p1 = Point{ x: -1, y: 2 };\n    let p2 = p1;\n    p1.x = 1;\n    println!(\"p1: {}, {}\", p1.x, p1.y);\n    println!(\"p2: {}, {}\", p2.x, p2.y);\n}\n```\n\nAlternatively, if we don't control the struct's definition, or mutable shared\nownership is truly required, we can use `Rc` and `RefCell`:\n\n```\nuse std::cell::RefCell;\nuse std::rc::Rc;\n\nstruct MyStruct { s: u32 }\n\nfn main() {\n    let mut x = Rc::new(RefCell::new(MyStruct{ s: 5u32 }));\n    let y = x.clone();\n    x.borrow_mut().s = 6;\n    println!(\"{}\", x.borrow().s);\n}\n```\n\nWith this approach, x and y share ownership of the data via the `Rc` (reference\ncount type). `RefCell` essentially performs runtime borrow checking: ensuring\nthat at most one writer or multiple readers can access the data at any one time.\n\nIf you wish to learn more about ownership in Rust, start with the chapter in the\nBook:\n\nhttps://doc.rust-lang.org/book/first-edition/ownership.html\n"},"level":"error","spans":[{"file_name":"/checkout/src/test/ui/borrowck/borrowck-loan-in-overloaded-op.rs","byte_start":800,"byte_end":801,"line_start":31,"line_end":31,"column_start":15,"column_end":16,"is_primary":false,"text":[{"text":"    let _y = {x} + x.clone(); // the `{x}` forces a move to occur","highlight_start":15,"highlight_end":16}],"label":"value moved here","suggested_replacement":null,"suggestion_applicability":null,"expansion":null},{"file_name":"/checkout/src/test/ui/borrowck/borrowck-loan-in-overloaded-op.rs","byte_start":805,"byte_end":806,"line_start":31,"line_end":31,"column_start":20,"column_end":21,"is_primary":true,"text":[{"text":"    let _y = {x} + x.clone(); // the `{x}` forces a move to occur","highlight_start":20,"highlight_end":21}],"label":"value borrowed here after move","suggested_replacement":null,"suggestion_applicability":null,"expansion":null}],"children":[{"message":"move occurs because `x` has type `Foo`, which does not implement the `Copy` trait","code":null,"level":"note","spans":[],"children":[],"rendered":null}],"rendered":"error[E0382]: borrow of moved value: `x`\n  --> /checkout/src/test/ui/borrowck/borrowck-loan-in-overloaded-op.rs:31:20\n   |\nLL |     let _y = {x} + x.clone(); // the `{x}` forces a move to occur\n   |               -    ^ value borrowed here after move\n   |               |\n   |               value moved here\n   |\n   = note: move occurs because `x` has type `Foo`, which does not implement the `Copy` trait\n\n"}

[01:20:27] {"message":"cannot move out of borrowed content","code":{"code":"E0507","explanation":"\nYou tried to move out of a value which was borrowed. Erroneous code example:\n\n```compile_fail,E0507\nuse std::cell::RefCell;\n\nstruct TheDarkKnight;\n\nimpl TheDarkKnight {\n    fn nothing_is_true(self) {}\n}\n\nfn main() {\n    let x = RefCell::new(TheDarkKnight);\n\n    x.borrow().nothing_is_true(); // error: cannot move out of borrowed content\n}\n```\n\nHere, the `nothing_is_true` method takes the ownership of `self`. However,\n`self` cannot be moved because `.borrow()` only provides an `&TheDarkKnight`,\nwhich is a borrow of the content owned by the `RefCell`. To fix this error,\nyou have three choices:\n\n* Try to avoid moving the variable.\n* Somehow reclaim the ownership.\n* Implement the `Copy` trait on the type.\n\nExamples:\n\n```\nuse std::cell::RefCell;\n\nstruct TheDarkKnight;\n\nimpl TheDarkKnight {\n    fn nothing_is_true(&self) {} // First case, we don't take ownership\n}\n\nfn main() {\n    let x = RefCell::new(TheDarkKnight);\n\n    x.borrow().nothing_is_true(); // ok!\n}\n```\n\nOr:\n\n```\nuse std::cell::RefCell;\n\nstruct TheDarkKnight;\n\nimpl TheDarkKnight {\n    fn nothing_is_true(self) {}\n}\n\nfn main() {\n    let x = RefCell::new(TheDarkKnight);\n    let x = x.into_inner(); // we get back ownership\n\n    x.nothing_is_true(); // ok!\n}\n```\n\nOr:\n\n```\nuse std::cell::RefCell;\n\n#[derive(Clone, Copy)] // we implement the Copy trait\nstruct TheDarkKnight;\n\nimpl TheDarkKnight {\n    fn nothing_is_true(self) {}\n}\n\nfn main() {\n    let x = RefCell::new(TheDarkKnight);\n\n    x.borrow().nothing_is_true(); // ok!\n}\n```\n\nMoving a member out of a mutably borrowed struct will also cause E0507 error:\n\n```compile_fail,E0507\nstruct TheDarkKnight;\n\nimpl TheDarkKnight {\n    fn nothing_is_true(self) {}\n}\n\nstruct Batcave {\n    knight: TheDarkKnight\n}\n\nfn main() {\n    let mut cave = Batcave {\n        knight: TheDarkKnight\n    };\n    let borrowed = &mut cave;\n\n    borrowed.knight.nothing_is_true(); // E0507\n}\n```\n\nIt is fine only if you put something back. `mem::replace` can be used for that:\n\n```\n# struct TheDarkKnight;\n# impl TheDarkKnight { fn nothing_is_true(self) {} }\n# struct Batcave { knight: TheDarkKnight }\nuse std::mem;\n\nlet mut cave = Batcave {\n    knight: TheDarkKnight\n};\nlet borrowed = &mut cave;\n\nmem::replace(&mut borrowed.knight, TheDarkKnight).nothing_is_true(); // ok!\n```\n\nYou can find more information about borrowing in the rust-book:\nhttp://doc.rust-lang.org/book/first-edition/references-and-borrowing.html\n"},"level":"error","spans":[{"file_name":"/checkout/src/test/ui/issues/issue-2590.rs","byte_start":632,"byte_end":643,"line_start":21,"line_end":21,"column_start":9,"column_end":20,"is_primary":true,"text":[{"text":"        self.tokens //~ ERROR cannot move out of borrowed content","highlight_start":9,"highlight_end":20}],"label":"cannot move out of borrowed content","suggested_replacement":null,"suggestion_applicability":null,"expansion":null}],"children":[],"rendered":"error[E0507]: cannot move out of borrowed content\n  --> /checkout/src/test/ui/issues/issue-2590.rs:21:9\n   |\nLL |         self.tokens //~ ERROR cannot move out of borrowed content\n   |         ^^^^^^^^^^^ cannot move out of borrowed content\n\n"}
