Struct gpu_descriptor::DescriptorAllocator

pub struct DescriptorAllocator<P, S> { /* private fields */ }

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

Implementations

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

pub fn new(max_update_after_bind_descriptors_in_all_pools: u32) -> Self

Create new allocator instance.

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.

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.

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.
