Module allocator

The allocator module.

The module provides custom memory allocator support traits and utilities based on the unstable feature(allocator_api).

Currently implemented as a reexport of parts of the [allocator_api2].

Macros

unsize_box

Allows turning a Box<T: Sized, A> into a Box<U: ?Sized, A> where T can be unsizing-coerced into a U.

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.

Box

A pointer type for heap allocation.

Global

The global memory allocator.

Traits

Allocator

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

TryCloneIn

Explicitly duplicate an object using the specified Allocator.

Functions

allocate

Moves value to the memory backed by alloc and returns a pointer.
