Expand description

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

Required Methods§

Source

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.

Source

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.

Source

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.

Source

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.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
