Structs

AllocError

The AllocError error indicates an allocation failure that may be due to resource exhaustion or to something wrong when combining the given input arguments with this allocator.

Traits

Allocator

An implementation of Allocator can allocate, grow, shrink, and deallocate arbitrary blocks of data described via Layout.

AllocatorCloneExperimental

Marks a type’s Clone implementation as sound with regard to Allocator equivalence. Implementors must ensure that, upon cloning, the two allocators are equivalent (i.e. it is possible to free memory with one that was allocated with the other). Further, mutable accesses such as moving or dropping the allocator must not invalidate its currently allocated blocks at least so long as clones exist.

AllocatorNightlyExperimental

Allocator marker trait that is only implemented stably for Global.

GlobalAllocatorExperimental

An Allocator that can be registered as the standard library’s default through the #[global_allocator] attribute.

StaticAllocatorExperimental

Marks that an allocator and its supertypes will never invalidate currently allocated memory unless explicitly deallocated via a call to a deallocating method, even if dropped or if the allocator’s lifetime expires.
