Struct vulkano::descriptor_set::persistent::PersistentDescriptorSet

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

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

Implementations

impl PersistentDescriptorSet

pub fn new(
    layout: Arc<DescriptorSetLayout>,
    descriptor_writes: impl IntoIterator<Item = WriteDescriptorSet>
) -> Result<Arc<PersistentDescriptorSet>, DescriptorSetCreationError>

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

See new_with_pool for more.

pub fn new_variable(
    layout: Arc<DescriptorSetLayout>,
    variable_descriptor_count: u32,
    descriptor_writes: impl IntoIterator<Item = WriteDescriptorSet>
) -> Result<Arc<PersistentDescriptorSet>, DescriptorSetCreationError>

Creates and returns a new descriptor set with the requested variable descriptor count.

See new_with_pool for more.

pub fn new_with_pool<P>(
    layout: Arc<DescriptorSetLayout>,
    variable_descriptor_count: u32,
    pool: &mut P,
    descriptor_writes: impl IntoIterator<Item = WriteDescriptorSet>
) -> Result<Arc<PersistentDescriptorSet<P::Alloc>>, DescriptorSetCreationError>where
    P: ?Sized + DescriptorPool,

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: DescriptorPoolAlloc,

fn inner(&self) -> &UnsafeDescriptorSet

Returns the inner UnsafeDescriptorSet.

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

Returns the layout of this descriptor set.

fn resources(&self) -> &DescriptorSetResources

Returns the resources bound to this descriptor set.

fn offsets<I>(self: Arc<Self>, dynamic_offsets: I) -> DescriptorSetWithOffsetswhere
    Self: Sized + 'static,
    I: IntoIterator<Item = u32>,

Creates a DescriptorSetWithOffsets with the given dynamic offsets.

impl<P> DeviceOwned for PersistentDescriptorSet<P>where
    P: DescriptorPoolAlloc,

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

Returns the device that owns Self.

impl<P> Hash for PersistentDescriptorSet<P>where
    P: DescriptorPoolAlloc,

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl<P> PartialEq<PersistentDescriptorSet<P>> for PersistentDescriptorSet<P>where
    P: DescriptorPoolAlloc,

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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