compiler/rustc_ast/src/ast.rs

 #[derive(Clone, Encodable, Decodable, Debug)]
 pub struct EnumDef {
-    pub variants: Vec<Variant>,
+    pub variants: Box<[Variant]>,


Maybe we could use std::boxed::ThinBox or something similar to further reduce the size from 16 to 8 bytes? By storing the slice size on the heap.

There is also thin_vec::ThinVec, which I introduced to the compiler in #100869. Unfortunately, getting any of these kinds of changes to show a clear performance benefit has been hard.

This one seems unlikely to produce any wins.
