pub struct FixedSizeDescriptorSetsPool<L> { /* private fields */ }
Expand description
Pool of descriptor sets of a specific capacity and that are automatically reclaimed.
You are encouraged to use this type when you need a different descriptor set at each frame, or regularly during the execution.
Example
At initialization, create a FixedSizeDescriptorSetsPool
. The first parameter of the new
function can be a graphics pipeline, a compute pipeline, or anything that represents a pipeline
layout.
use vulkano::descriptor::descriptor_set::FixedSizeDescriptorSetsPool;
// use vulkano::pipeline::GraphicsPipelineAbstract;
// let graphics_pipeline: Arc<GraphicsPipelineAbstract> = ...;
let pool = FixedSizeDescriptorSetsPool::new(graphics_pipeline.clone(), 0);
You would then typically store the pool in a struct for later. Its type is
FixedSizeDescriptorSetsPool<T>
where T
is the type of what was passed to new()
. In the
example above, it would be FixedSizeDescriptorSetsPool<Arc<GraphicsPipelineAbstract>>
.
Then whenever you need a descriptor set, call pool.next()
to start the process of building
it.
let descriptor_set = pool.next()
//.add_buffer(...)
//.add_sampled_image(...)
.build().unwrap();
Note that next()
requires exclusive (mut
) access to the pool. You can use a Mutex
around
the pool if you can’t provide this.
Implementations
sourceimpl<L> FixedSizeDescriptorSetsPool<L>
impl<L> FixedSizeDescriptorSetsPool<L>
sourcepub fn new(layout: L, set_id: usize) -> FixedSizeDescriptorSetsPool<L>where
L: PipelineLayoutAbstract,
pub fn new(layout: L, set_id: usize) -> FixedSizeDescriptorSetsPool<L>where
L: PipelineLayoutAbstract,
Initializes a new pool. The pool is configured to allocate sets that corresponds to the parameters passed to this function.
sourcepub fn next(&mut self) -> FixedSizeDescriptorSetBuilder<'_, L, ()>where
L: PipelineLayoutAbstract + Clone,
pub fn next(&mut self) -> FixedSizeDescriptorSetBuilder<'_, L, ()>where
L: PipelineLayoutAbstract + Clone,
Starts the process of building a new descriptor set.
The set will corresponds to the set layout that was passed to new
.
