Struct sp_std::alloc::Global[−][src]

pub struct Global;

🔬 This is a nightly-only experimental API. (allocator_api)

The global memory allocator.

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

Note: while this type is unstable, the functionality it provides can be accessed through the free functions in alloc.
