Struct UsmAllocator 

pub struct UsmAllocator<'a, T: UsmAllocatorKind> { /* private fields */ }

An instance of a USM allocator.

Trait Implementations

impl<T: UsmAllocatorKind> Allocator for UsmAllocator<'_, T>

fn allocate(&self, layout: Layout) -> Result<NonNull<[u8]>, AllocError>

Attempts to allocate a block of memory.

unsafe fn deallocate(&self, ptr: NonNull<u8>, _layout: Layout)

Deallocates the memory referenced by ptr.

fn allocate_zeroed(&self, layout: Layout) -> Result<NonNull<[u8]>, AllocError>

Behaves like allocate, but also ensures that the returned memory is zero-initialized.

unsafe fn grow( &self, ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

Attempts to extend the memory block.

unsafe fn grow_zeroed( &self, ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

Behaves like grow, but also ensures that the new contents are set to zero before being returned.

unsafe fn shrink( &self, ptr: NonNull<u8>, old_layout: Layout, new_layout: Layout, ) -> Result<NonNull<[u8]>, AllocError>

Attempts to shrink the memory block.

fn by_ref(&self) -> &Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Allocator.

impl<'a, T: UsmAllocatorKind> From<&'a Queue> for UsmAllocator<'a, T>

fn from(queue: &'a Queue) -> Self

Converts to this type from the input type.
