Struct ccthw_ash_allocator::DedicatedAllocator

pub struct DedicatedAllocator<A: ComposableAllocator, B: ComposableAllocator> { /* private fields */ }

An allocator which correctly handles allocations which prefer or require dedicated allocations.

Implementations

impl<A, B> DedicatedAllocator<A, B>where A: ComposableAllocator, B: ComposableAllocator,

pub fn new(allocator: A, device_allocator: B) -> Self

Create a new dedicated allocator which decorates another allocator implementation to properly handle dedicated resources.

Param

• allocator: The allocator to decorate.
• device_allocator: An allocator which directly returns memory from the device itself.
