Struct gpu_descriptor::DescriptorAllocator

source ·
pub struct DescriptorAllocator<P, S> { /* private fields */ }
Expand description

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

Implementations§

source§

impl<P, S> DescriptorAllocator<P, S>

source

pub fn new(max_update_after_bind_descriptors_in_all_pools: u32) -> Self

Create new allocator instance.

source

pub unsafe fn allocate<L, D>( &mut self, device: &D, layout: &L, flags: DescriptorSetLayoutCreateFlags, layout_descriptor_count: &DescriptorTotalCount, count: u32 ) -> Result<Vec<DescriptorSet<S>>, AllocationError>
where S: Debug, L: Debug, D: DescriptorDevice<L, P, S>,

Allocate descriptor set with specified layout.

§Safety
  • Same device instance must be passed to all method calls of one DescriptorAllocator instance.
  • flags must match flags that were used to create the layout.
  • layout_descriptor_count must match descriptor numbers in the layout.
source

pub unsafe fn free<L, D, I>(&mut self, device: &D, sets: I)
where D: DescriptorDevice<L, P, S>, I: IntoIterator<Item = DescriptorSet<S>>,

Free descriptor sets.

§Safety
  • Same device instance must be passed to all method calls of one DescriptorAllocator instance.
  • None of descriptor sets can be referenced in any pending command buffers.
  • All command buffers where at least one of descriptor sets referenced move to invalid state.
source

pub unsafe fn cleanup<L>(&mut self, device: &impl DescriptorDevice<L, P, S>)

Perform cleanup to allow resources reuse.

§Safety
  • Same device instance must be passed to all method calls of one DescriptorAllocator instance.
