Module allocator_api::alloc [−] [src]

Structs

AllocErr	The `AllocErr` error specifies whether an allocation failure is specifically due to resource exhaustion or if it is due to something wrong when combining the given input arguments with this allocator.
CannotReallocInPlace	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	Represents the combination of a starting address and a total capacity of the returned block.
Layout	Layout of a block of memory.
LayoutErr	The parameters given to `Layout::from_size_align` do not satisfy its documented constraints.

CollectionAllocErr	Augments `AllocErr` with a CapacityOverflow variant.
Opaque	An opaque, unsized type. Used for pointers to allocated memory.

Alloc	An implementation of `Alloc` can allocate, reallocate, and deallocate arbitrary blocks of data described via `Layout`.
GlobalAlloc	A memory allocator that can be registered to be the one backing `std::alloc::Global` though the `#[global_allocator]` attributes.
