Add cfg(foundations_jemalloc_disable) to opt out of global jemalloc allocator#216
Merged
Conversation
…llocator Usually our advice would be to not enable the `jemalloc` cargo feature, but this becomes difficult in large dependency trees where a user may not necessarily control all dependencies that in turn depend on foundations. Providing a flag to disable the `#[global_allocator]` specifically allows such projects to build anyway. This is also useful to enable ASAN builds, which otherwise wouldn't cover allocations initiated from Rust.
