Struct vulkano::shader::DescriptorRequirements

pub struct DescriptorRequirements {
    pub memory_read: ShaderStages,
    pub memory_write: ShaderStages,
    pub sampler_compare: bool,
    pub sampler_no_unnormalized_coordinates: bool,
    pub sampler_no_ycbcr_conversion: bool,

The requirements imposed by a shader on resources bound to a descriptor.

Fields

memory_read: ShaderStages

For buffers and images, which shader stages perform read operations.

memory_write: ShaderStages

For buffers and images, which shader stages perform write operations.

sampler_compare: bool

For sampler bindings, whether the shader performs depth comparison operations.

sampler_no_unnormalized_coordinates: bool

For sampler bindings, whether the shader performs sampling operations that are not permitted with unnormalized coordinates. This includes sampling with ImplicitLod, Dref or Proj SPIR-V instructions or with an LOD bias or offset.

sampler_no_ycbcr_conversion: bool

For sampler bindings, whether the shader performs sampling operations that are not permitted with a sampler YCbCr conversion. This includes sampling with Gather SPIR-V instructions or with an offset.

sampler_with_images: HashSet<DescriptorIdentifier>

For sampler bindings, the sampled image descriptors that are used in combination with this sampler.

storage_image_atomic: bool

For storage image bindings, whether the shader performs atomic operations.

Implementations

impl DescriptorRequirements

pub fn merge(&mut self, other: &Self)

Merges other into self, so that self satisfies the requirements of both.

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.
