Struct vulkano::descriptor::descriptor::DescriptorDesc [−][src]
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: DescriptorDescTy
Describes the content and layout of each array element of a descriptor.
array_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.
stages: ShaderStages
Which shader stages are going to access this descriptor.
readonly: bool
True if the attachment is only ever read by the shader. False if it is also written.
Implementations
impl DescriptorDesc
[src]
pub fn is_superset_of(
&self,
other: &DescriptorDesc
) -> Result<(), DescriptorDescSupersetError>
[src]
&self,
other: &DescriptorDesc
) -> Result<(), DescriptorDescSupersetError>
Checks whether we are a superset of another descriptor.
Returns true if self
is the same descriptor as other
, or if self
is the same as
other
but with a larger array elements count and/or more shader stages.
Example
use vulkano::descriptor::descriptor::DescriptorDesc; use vulkano::descriptor::descriptor::DescriptorDescTy::*; use vulkano::descriptor::descriptor::ShaderStages; let desc_super = DescriptorDesc{ ty: Sampler, array_count: 2, stages: ShaderStages{ vertex: true, tessellation_control: true, tessellation_evaluation: true, geometry: true, fragment: true, compute: true }, readonly: false }; let desc_sub = DescriptorDesc{ ty: Sampler, array_count: 1, stages: ShaderStages{ vertex: true, tessellation_control: false, tessellation_evaluation: false, geometry: false, fragment: true, compute: false }, readonly: true }; assert_eq!(desc_super.is_superset_of(&desc_sub).unwrap(), ());
pub fn union(&self, other: &DescriptorDesc) -> Option<DescriptorDesc>
[src]
Builds a DescriptorDesc
that is the union of self
and other
, if possible.
The returned value will be a superset of both self
and other
.
Example
use vulkano::descriptor::descriptor::DescriptorDesc; use vulkano::descriptor::descriptor::DescriptorDescTy::*; use vulkano::descriptor::descriptor::ShaderStages; let desc_part1 = DescriptorDesc{ ty: Sampler, array_count: 2, stages: ShaderStages{ vertex: true, tessellation_control: true, tessellation_evaluation: false, geometry: true, fragment: false, compute: true }, readonly: false }; let desc_part2 = DescriptorDesc{ ty: Sampler, array_count: 1, stages: ShaderStages{ vertex: true, tessellation_control: false, tessellation_evaluation: true, geometry: false, fragment: true, compute: true }, readonly: true }; let desc_union = DescriptorDesc{ ty: Sampler, array_count: 2, stages: ShaderStages{ vertex: true, tessellation_control: true, tessellation_evaluation: true, geometry: true, fragment: true, compute: true }, readonly: false }; assert_eq!(desc_part1.union(&desc_part2), Some(desc_union));
pub fn pipeline_stages_and_access(&self) -> (PipelineStages, AccessFlagBits)
[src]
Returns the pipeline stages and access flags corresponding to the usage of this descriptor.
Panic
Panics if the type is Sampler
.
