Abstract device that can create pools of type P and allocate sets S with layout L.

Required Methods

unsafe fn create_descriptor_pool( &self, descriptor_count: &DescriptorTotalCount, max_sets: u32, flags: DescriptorPoolCreateFlags, ) -> Result<P, CreatePoolError>

Creates a new descriptor pool.

Safety

Actually safe. TODO: Remove unsafe with next breaking change.

unsafe fn destroy_descriptor_pool(&self, pool: P)

Destroys descriptor pool.

Safety

Pool must be created from this device. All descriptor sets allocated from this pool become invalid.

unsafe fn alloc_descriptor_sets<'a>( &self, pool: &mut P, layouts: impl ExactSizeIterator<Item = &'a L>, sets: &mut impl Extend<S>, ) -> Result<(), DeviceAllocationError>

where L: 'a,

Allocates descriptor sets.

Safety

Pool must be created from this device.

unsafe fn dealloc_descriptor_sets( &self, pool: &mut P, sets: impl Iterator<Item = S>, )

Deallocates descriptor sets.

Safety

Sets must be allocated from specified pool and not deallocated before.

Object Safety

This trait is not object safe.
