Struct vulkano::shader::DescriptorBindingRequirements

pub struct DescriptorBindingRequirements {
    pub descriptor_types: Vec<DescriptorType>,
    pub descriptor_count: Option<u32>,
    pub image_format: Option<Format>,
    pub image_multisampled: bool,
    pub image_scalar_type: Option<NumericType>,

}

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

Fields

descriptor_types: Vec<DescriptorType>

The descriptor types that are allowed.

descriptor_count: Option<u32>

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

None means that the shader declares this as a runtime-sized array, and could potentially access every array element provided in the descriptor set.

image_format: Option<Format>

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

image_multisampled: bool

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

image_scalar_type: Option<NumericType>

The base scalar type required for the format of image views bound to this binding. This is None for non-image bindings.

image_view_type: Option<ImageViewType>

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

stages: ShaderStages

The shader stages that the binding must be declared for.

descriptors: HashMap<Option<u32>, DescriptorRequirements>

The requirements for individual descriptors within a binding.

Keys with Some hold requirements for a specific descriptor index, if it is statically known in the shader (a constant). The key None holds requirements for indices that are not statically known, but determined only at runtime (calculated from an input variable).

Implementations

impl DescriptorBindingRequirements

pub fn merge(&mut self, other: &Self) -> Result<(), Box<ValidationError>>

Merges other into self, so that self satisfies the requirements of both. An error is returned if the requirements conflict.

Trait Implementations

impl Clone for DescriptorBindingRequirements

fn clone(&self) -> DescriptorBindingRequirements

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DescriptorBindingRequirements

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

Formats the value using the given formatter.

impl Default for DescriptorBindingRequirements

fn default() -> DescriptorBindingRequirements

Returns the “default value” for a type.

impl From<&DescriptorBindingRequirements> for DescriptorSetLayoutBinding

fn from(reqs: &DescriptorBindingRequirements) -> Self

Converts to this type from the input type.
