[][src]Struct alloc::alloc::Global

pub struct Global;
🔬 This is a nightly-only experimental API. (allocator_api #32838)

The global memory allocator.

This type implements the Alloc trait by forwarding calls to the allocator registered with the #[global_allocator] attribute if there is one, or the std crate’s default.
