Struct ccthw_ash_allocator::MemoryTypePoolAllocator

pub struct MemoryTypePoolAllocator<Allocator: ComposableAllocator> { /* private fields */ }

Implementations

impl<Allocator: ComposableAllocator> MemoryTypePoolAllocator<Allocator>

pub fn new( memory_type_index: usize, chunk_size: u64, page_size: u64, allocator: Allocator ) -> Self

Create a new pool for a particular memory type index.

Params

• memory_type_index: the index of the specific memory type this pool can allocate from.
• chunk_size: the size of each chunk of memory to be divided into pages.
• page_size: chunks are divided into pages with this size for allocation.
• allocator: the backing allocator which provides device memory.
