Struct ccthw::graphics::vulkan_api::raii::DescriptorPool

pub struct DescriptorPool { /* private fields */ }

RAII Vulkan DescriptorPool.

Implementations

impl DescriptorPool

pub unsafe fn new( render_device: Arc<RenderDevice>, create_info: &DescriptorPoolCreateInfo ) -> Result<Self, GraphicsError>

Create a new Vulkan descriptor pool.

Safety

Unsafe because:

• command pools must be destroyed before the Vulkan device is dropped.

pub unsafe fn new_with_sizes( render_device: Arc<RenderDevice>, max_sets: u32, pool_sizes: &[DescriptorPoolSize] ) -> Result<Self, GraphicsError>

Create a new Vulkan descriptor pool using the max_sets and pool_sizes.

Safety

Unsafe because:

• command pools must be destroyed before the Vulkan device is dropped.

pub fn set_debug_name(&self, name: impl Into<String>)

Set the name which shows up in Vulkan debug logs for this resource.

pub fn descriptor_set(&self, index: usize) -> DescriptorSet

Get the n’th descriptor set owned by this pool.

Note: The descriptor pool destroys all allocated sets when it is dropped. The caller must ensure that no descriptor sets are kept around after the pool is dropped.

pub fn allocate_descriptor_sets( &mut self, layouts: &[&DescriptorSetLayout] ) -> Result<usize, GraphicsError>

Allocate descriptor sets from this pool.

Returns

Returns the index of the first newly allocated descriptor set.

pub fn raw(&self) -> DescriptorPool

Get the raw Vulkan command pool handle.
