Trait for objects that describe the layout of the descriptors and push constants of a pipeline.

Required methods

fn num_sets(&self) -> usize

Returns the number of sets in the layout. Includes possibly empty sets.

In other words, this should be equal to the highest set number plus one.

fn num_bindings_in_set(&self, set: usize) -> Option<usize>

Returns the number of descriptors in the set. Includes possibly empty descriptors.

Returns None if the set is out of range.

fn descriptor(&self, set: usize, binding: usize) -> Option<DescriptorDesc>

Returns the descriptor for the given binding of the given set.

Returns None if out of range or if the descriptor is empty.

fn num_push_constants_ranges(&self) -> usize

Returns the number of push constant ranges of the layout.

fn push_constants_range(&self, num: usize) -> Option<PipelineLayoutDescPcRange>

Returns a description of the given push constants range.

Contrary to the descriptors, a push constants range can't be empty.

Returns None if out of range.

Each bit of stages must only be present in a single push constants range of the description.

Provided methods

fn provided_set_layout(
    &self,
    _set: usize
) -> Option<Arc<UnsafeDescriptorSetLayout>>

If the PipelineLayoutDesc implementation is able to provide an existing UnsafeDescriptorSetLayout for a given set, it can do so by returning it here.

fn union<T>(self, other: T) -> PipelineLayoutDescUnion<Self, T> where
    Self: Sized, 

Builds the union of this layout and another.

fn check_against_limits(
    &self,
    device: &Device
) -> Result<(), PipelineLayoutLimitsError>

Checks whether this description fulfills the device limits requirements.

fn build(
    self,
    device: Arc<Device>
) -> Result<PipelineLayout<Self>, PipelineLayoutCreationError> where
    Self: Sized, 

Turns the layout description into a PipelineLayout object that can be used by Vulkan.

Note: This is just a shortcut for PipelineLayout::new.
