Struct nannou::vk::DescriptorDesc

pub struct DescriptorDesc {
    pub ty: DescriptorDescTy,
    pub array_count: u32,
    pub stages: ShaderStages,
    pub readonly: bool,
}

Contains the exact description of a single descriptor.

Note: You are free to fill a DescriptorDesc struct the way you want, but its validity will be checked when you create a pipeline layout, a descriptor set, or when you try to bind a descriptor set.

Fields

ty: DescriptorDescTy

Describes the content and layout of each array element of a descriptor.

array_count: u32

How many array elements this descriptor is made of. The value 0 is invalid and may trigger a panic depending on the situation.

stages: ShaderStages

Which shader stages are going to access this descriptor.

readonly: bool

True if the attachment is only ever read by the shader. False if it is also written.

Methods

impl DescriptorDesc

pub fn is_superset_of(
    &self,
    other: &DescriptorDesc
) -> Result<(), DescriptorDescSupersetError>

Checks whether we are a superset of another descriptor.

Returns true if self is the same descriptor as other, or if self is the same as other but with a larger array elements count and/or more shader stages.

pub fn union(&self, other: &DescriptorDesc) -> Option<DescriptorDesc>

Builds a DescriptorDesc that is the union of self and other, if possible.

The returned value will be a superset of both self and other.

pub fn pipeline_stages_and_access(&self) -> (PipelineStages, AccessFlagBits)

Returns the pipeline stages and access flags corresponding to the usage of this descriptor.

Panic

Panics if the type is Sampler.

Trait Implementations

impl Debug for DescriptorDesc

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Clone for DescriptorDesc

fn clone(&self) -> DescriptorDesc

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
