Struct vulkano::descriptor_set::layout::DescriptorDesc

pub struct DescriptorDesc {
    pub ty: DescriptorType,
    pub descriptor_count: u32,
    pub variable_count: bool,
    pub stages: ShaderStages,
    pub immutable_samplers: Vec<Arc<Sampler>>,
}

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: DescriptorType

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

descriptor_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.

variable_count: bool

True if the descriptor has a variable descriptor count. The value of descriptor_count is taken as the maximum number of descriptors allowed. There may only be one binding with a variable count in a descriptor set, and it must be the last binding.

stages: ShaderStages

Which shader stages are going to access this descriptor.

immutable_samplers: Vec<Arc<Sampler>>

Samplers that are included as a fixed part of the descriptor set layout. Once bound, they do not need to be provided when creating a descriptor set.

The list must be either empty, or contain exactly descriptor_count samplers. It must be empty if ty is something other than Sampler or CombinedImageSampler.

Implementations

impl DescriptorDesc

pub fn ensure_compatible_with_shader(
    &self,
    descriptor_requirements: &DescriptorRequirements
) -> Result<(), DescriptorRequirementsNotMet>

Checks whether the descriptor of a pipeline layout self is compatible with the descriptor of a shader other.

Trait Implementations

fn clone(&self) -> DescriptorDesc

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DescriptorDesc

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