Memory allocation APIs

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.
CannotReallocInPlace	[ Experimental ] The CannotReallocInPlace error is used when grow_in_place or shrink_in_place were unable to reuse the given memory block for a requested layout.
Excess	[ Experimental ] Represents the combination of a starting address and a total capacity of the returned block.
Global	[ Experimental ] The global memory allocator.

Traits

GlobalAlloc	A memory allocator that can be registered as the standard library’s default though the #[global_allocator] attributes.
Alloc	[ Experimental ] An implementation of Alloc can allocate, reallocate, and deallocate arbitrary blocks of data described via Layout.

Functions

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.
