Struct Heaps

pub struct Heaps<B: Backend> { /* private fields */ }

Heaps available on particular physical device.

Implementations

impl<B> Heaps<B>

where B: Backend,

pub unsafe fn new<P, H>(types: P, heaps: H) -> Self

where P: IntoIterator<Item = (Properties, u32, HeapsConfig)>, H: IntoIterator<Item = u64>,

This must be called with gfx_hal::memory::Properties fetched from physical device.

pub fn allocate( &mut self, device: &B::Device, mask: u32, usage: impl MemoryUsage, size: u64, align: u64, ) -> Result<MemoryBlock<B>, HeapsError>

Allocate memory block from one of memory types specified by mask, for intended usage, with size and align requirements.

pub fn free(&mut self, device: &B::Device, block: MemoryBlock<B>)

Free memory block.

Memory block must be allocated from this heap.

pub fn dispose(self, device: &B::Device)

Dispose of allocator. Cleanup allocators before dropping. Will panic if memory instances are left allocated.

pub fn utilization(&self) -> TotalMemoryUtilization

Get memory utilization.

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

Formats the value using the given formatter.
