Struct alloc::alloc::Global [−][src]
pub struct Global;
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
.
