Memory allocation APIs

In a given program, the standard library has one “global” memory allocator that is used for example by Box<T> and Vec<T>.

Structs

Layout	Layout of a block of memory.
LayoutErr	The parameters given to `Layout::from_size_align` or some other `Layout` constructor do not satisfy its documented constraints.
AllocErr	Experimental The `AllocErr` 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.
Global	Experimental The global memory allocator.
MemoryBlock	Experimental Represents a block of allocated memory returned by an allocator.
System

AllocInit	Experimental A desired initial state for allocated memory.
ReallocPlacement	Experimental A placement constraint when growing or shrinking an existing allocation.

GlobalAlloc	A memory allocator that can be registered as the standard library’s default through the `#[global_allocator]` attribute.
AllocRef	Experimental An implementation of `AllocRef` can allocate, grow, shrink, and deallocate arbitrary blocks of data described via `Layout`.

alloc ^⚠	Allocate memory with the global allocator.
alloc_zeroed ^⚠	Allocate zero-initialized memory with the global allocator.
dealloc ^⚠	Deallocate memory with the global allocator.
handle_alloc_error	Abort on memory allocation error or failure.
realloc ^⚠	Reallocate memory with the global allocator.
set_alloc_error_hook	Registers a custom allocation error hook, replacing any that was previously registered.
take_alloc_error_hook	Unregisters the current allocation error hook, returning it.
