[−][src]Struct vulkano::descriptor::descriptor_set::FixedSizeDescriptorSetsPool
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
.
use vulkano::descriptor::descriptor_set::FixedSizeDescriptorSetsPool; use vulkano::descriptor::pipeline_layout::PipelineLayoutAbstract; // use vulkano::pipeline::GraphicsPipelineAbstract; // let graphics_pipeline: Arc<GraphicsPipelineAbstract> = ...; let layout = graphics_pipeline.descriptor_set_layout(0).unwrap(); let pool = FixedSizeDescriptorSetsPool::new(layout.clone());
You would then typically store the pool in a struct for later. 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.
Methods
impl FixedSizeDescriptorSetsPool
[src]
pub fn new(
layout: Arc<UnsafeDescriptorSetLayout>
) -> FixedSizeDescriptorSetsPool
[src]
layout: Arc<UnsafeDescriptorSetLayout>
) -> FixedSizeDescriptorSetsPool
Initializes a new pool. The pool is configured to allocate sets that corresponds to the parameters passed to this function.
pub fn next(&mut self) -> FixedSizeDescriptorSetBuilder<()>
[src]
Starts the process of building a new descriptor set.
The set will corresponds to the set layout that was passed to new
.
