Struct vulkano::descriptor_set::layout::DescriptorSetLayoutCreateInfo

pub struct DescriptorSetLayoutCreateInfo {
    pub bindings: BTreeMap<u32, DescriptorSetLayoutBinding>,
    pub push_descriptor: bool,
    pub _ne: NonExhaustive,
}

Parameters to create a new DescriptorSetLayout.

Fields

bindings: BTreeMap<u32, DescriptorSetLayoutBinding>

The bindings of the desriptor set layout. These are specified according to binding number.

It is generally advisable to keep the binding numbers low. Higher binding numbers may use more memory inside Vulkan.

The default value is empty.

push_descriptor: bool

Whether the descriptor set layout should be created for push descriptors.

If true, the layout can only be used for push descriptors, and if false, it can only be used for regular descriptor sets.

If set to true, the khr_push_descriptor extension must be enabled on the device, and there are several restrictions:

• There must be no bindings with a type of DescriptorType::UniformBufferDynamic or DescriptorType::StorageBufferDynamic.
• There must be no bindings with variable_descriptor_count enabled.
• The total number of descriptors across all bindings must be less than the max_push_descriptors limit.

The default value is false.

_ne: NonExhaustive

Implementations

impl DescriptorSetLayoutCreateInfo

pub fn from_requirements<'a>(
    descriptor_requirements: impl IntoIterator<Item = ((u32, u32), &'a DescriptorRequirements)>
) -> Vec<Self>

Builds a list of DescriptorSetLayoutCreateInfo from an iterator of DescriptorRequirement originating from a shader.
