Struct rendy_descriptor::DescriptorAllocator

pub struct DescriptorAllocator<B: Backend> { /* fields omitted */ }

Descriptor allocator. Can be used to allocate descriptor sets for any layout.

Methods

impl<B> DescriptorAllocator<B> where
    B: Backend, 

pub fn new() -> Self

Create new allocator instance.

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

Destroy allocator instance. All sets allocated from this allocator become invalid.

pub unsafe fn allocate(
    &mut self,
    device: &B::Device,
    layout: &B::DescriptorSetLayout,
    layout_ranges: DescriptorRanges,
    count: u32,
    extend: &mut impl Extend<DescriptorSet<B>>
) -> Result<(), OutOfMemory>

Allocate descriptor set with specified layout. DescriptorRanges must match descriptor numbers of the layout. DescriptorRanges can be constructed from bindings that were used to create layout instance.

pub unsafe fn free(
    &mut self,
    all_sets: impl IntoIterator<Item = DescriptorSet<B>>
)

Free descriptor sets.

Safety

None of descriptor sets can be refernced in any pending command buffers. All command buffers where at least one of descriptor sets referenced move to invalid state.

pub unsafe fn cleanup(&mut self, device: &B::Device)

Perform cleanup to allow resources reuse.

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

Formats the value using the given formatter.
