Struct PersistentDescriptorSet 

pub struct PersistentDescriptorSet<P = StandardDescriptorSetAlloc> { /* private fields */ }

A simple, immutable descriptor set that is expected to be long-lived.

Implementations

impl PersistentDescriptorSet

pub fn new<A>( allocator: &A, layout: Arc<DescriptorSetLayout>, descriptor_writes: impl IntoIterator<Item = WriteDescriptorSet>, descriptor_copies: impl IntoIterator<Item = CopyDescriptorSet>, ) -> Result<Arc<PersistentDescriptorSet<<A as DescriptorSetAllocator>::Alloc>>, Validated<VulkanError>>

where A: DescriptorSetAllocator + ?Sized,

Creates and returns a new descriptor set with a variable descriptor count of 0.

See new_with_pool for more.

pub fn new_variable<A>( allocator: &A, layout: Arc<DescriptorSetLayout>, variable_descriptor_count: u32, descriptor_writes: impl IntoIterator<Item = WriteDescriptorSet>, descriptor_copies: impl IntoIterator<Item = CopyDescriptorSet>, ) -> Result<Arc<PersistentDescriptorSet<<A as DescriptorSetAllocator>::Alloc>>, Validated<VulkanError>>

where A: DescriptorSetAllocator + ?Sized,

Creates and returns a new descriptor set with the requested variable descriptor count, allocating it from the provided pool.

Panics

• Panics if layout was created for push descriptors rather than descriptor sets.
• Panics if variable_descriptor_count is too large for the given layout.

Trait Implementations

impl<P> DescriptorSet for PersistentDescriptorSet<P>

where P: DescriptorSetAlloc,

fn alloc(&self) -> &DescriptorPoolAlloc

Returns the allocation of the descriptor set.

fn pool(&self) -> &DescriptorPool

Returns the descriptor pool that the descriptor set was allocated from.

fn resources(&self) -> &DescriptorSetResources

Returns the resources bound to this descriptor set.

fn layout(&self) -> &Arc<DescriptorSetLayout>

Returns the layout of this descriptor set.

fn variable_descriptor_count(&self) -> u32

Returns the variable descriptor count that this descriptor set was allocated with.

fn offsets( self: Arc<Self>, dynamic_offsets: impl IntoIterator<Item = u32>, ) -> DescriptorSetWithOffsets

where Self: Sized + 'static,

Creates a DescriptorSetWithOffsets with the given dynamic offsets.

impl<P> DeviceOwned for PersistentDescriptorSet<P>

where P: DescriptorSetAlloc,

fn device(&self) -> &Arc<Device>

Returns the device that owns self.

impl<P> Hash for PersistentDescriptorSet<P>

where P: DescriptorSetAlloc,

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<P> PartialEq for PersistentDescriptorSet<P>

where P: DescriptorSetAlloc,

fn eq(&self, other: &PersistentDescriptorSet<P>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<P> VulkanObject for PersistentDescriptorSet<P>

where P: DescriptorSetAlloc,

type Handle = DescriptorSet

The type of the object.

fn handle(&self) -> <PersistentDescriptorSet<P> as VulkanObject>::Handle

Returns the raw Vulkan handle of the object.

impl<P> Eq for PersistentDescriptorSet<P>

where P: DescriptorSetAlloc,
