Struct ccthw_ash_allocator::SizedAllocator

pub struct SizedAllocator<SmallAllocator: ComposableAllocator, LargeAllocator: ComposableAllocator> { /* private fields */ }

An allocator which composes over two other allocators. When a request is below the trigger size, it is sent to the first alloctor, otherwise it is sent to the second allocator.

Implementations

impl<S, L> SizedAllocator<S, L>where S: ComposableAllocator, L: ComposableAllocator,

pub fn new(size_trigger: u64, small_allocator: S, large_allocator: L) -> Self

Create a new allocator which routes requests based on the allocation size.

Trait Implementations

impl<S, L> ComposableAllocator for SizedAllocator<S, L>where S: ComposableAllocator, L: ComposableAllocator,

unsafe fn allocate( &mut self, allocation_requirements: AllocationRequirements ) -> Result<Allocation, AllocatorError>

Allocate GPU memory based on the given requirements.

unsafe fn free(&mut self, allocation: Allocation)

Return a GPU memory allocation to the device.
