Struct rendy_memory::DedicatedAllocator

pub struct DedicatedAllocator { /* fields omitted */ }

Dedicated memory allocator that uses memory object per allocation requested.

This allocator suites best huge allocations. From 32 MiB when GPU has 4-8 GiB memory total.

Heaps use this allocator when none of sub-allocators bound to the memory type can handle size required. TODO: Check if resource prefers dedicated memory.

Methods

impl DedicatedAllocator

pub fn properties_required() -> Properties

Get properties required by the allocator.

pub fn new(memory_type: MemoryTypeId, memory_properties: Properties) -> Self

Create new LinearAllocator for memory_type with memory_properties specified

Trait Implementations

impl<B> Allocator<B> for DedicatedAllocator where
    B: Backend, 

type Block = DedicatedBlock<B>

Block type returned by allocator.

fn kind() -> Kind

Get allocator kind.

fn alloc(
    &mut self,
    device: &B::Device,
    size: u64,
    _align: u64
) -> Result<(DedicatedBlock<B>, u64), AllocationError>

Allocate block of memory. On success returns allocated block and amount of memory consumed from device.

fn free(&mut self, device: &B::Device, block: DedicatedBlock<B>) -> u64

Free block of memory. Returns amount of memory returned to the device.

impl Drop for DedicatedAllocator

fn drop(&mut self)

Executes the destructor for this type.

impl Debug for DedicatedAllocator

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
