Struct vulkano::shader::DescriptorRequirements

pub struct DescriptorRequirements {
    pub descriptor_types: Vec<DescriptorType>,
    pub descriptor_count: u32,
    pub format: Option<Format>,
    pub image_view_type: Option<ImageViewType>,
    pub multisampled: bool,
    pub mutable: bool,
    pub stages: ShaderStages,
}

The requirements imposed by a shader on a descriptor within a descriptor set layout, and on any resource that is bound to that descriptor.

Fields

descriptor_types: Vec<DescriptorType>

The descriptor types that are allowed.

descriptor_count: u32

The number of descriptors (array elements) that the shader requires. The descriptor set layout can declare more than this, but never less.

format: Option<Format>

The image format that is required for image views bound to this descriptor. If this is None, then any image format is allowed.

image_view_type: Option<ImageViewType>

The view type that is required for image views bound to this descriptor. This is None for non-image descriptors.

multisampled: bool

Whether image views bound to this descriptor must have multisampling enabled or disabled.

mutable: bool

Whether the shader requires mutable (exclusive) access to the resource bound to this descriptor.

stages: ShaderStages

The shader stages that the descriptor must be declared for.

Implementations

impl DescriptorRequirements

pub fn intersection(
    &self,
    other: &Self
) -> Result<Self, DescriptorRequirementsIncompatible>

Produces the intersection of two descriptor requirements, so that the requirements of both are satisfied. An error is returned if the requirements conflict.

Trait Implementations

impl Clone for DescriptorRequirements

fn clone(&self) -> DescriptorRequirements

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DescriptorRequirements

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

Formats the value using the given formatter.

impl Default for DescriptorRequirements

fn default() -> DescriptorRequirements

Returns the “default value” for a type.

impl From<&'_ DescriptorRequirements> for DescriptorDesc

fn from(reqs: &DescriptorRequirements) -> Self

Performs the conversion.
