Khronos reference: VkDescriptorSetAllocateInfo

Fields

s_type: StructureType

Native field sType.

p_next: *const c_void

Native field pNext.

descriptor_pool: DescriptorPool

Native field descriptorPool.

descriptor_set_count: u32

Native field descriptorSetCount.

p_set_layouts: *const DescriptorSetLayout

Native field pSetLayouts.

Implementations

impl<'a> DescriptorSetAllocateInfo<'a>

pub fn new() -> Self

Construct the record with its canonical sType tag and default native state.

pub fn set_descriptor_pool(self, value: DescriptorPool) -> Self

Set native field descriptorPool without native effects.

pub fn set_descriptor_set_count(self, value: u32) -> Self

Set native count descriptorSetCount directly without checking associated pointer extents. Use the borrowed array helpers to derive matching storage and counts together. Direct count edits support null-query/dynamic-state paths and remain a native-call validity obligation, including after earlier borrowed setters.

pub fn set_set_layouts( self, value: &'a [DescriptorSetLayout], ) -> Result<Self, ConstructionError>

Borrow pSetLayouts and set checked native count descriptorSetCount. The borrow covers this storage only; nested raw pointers, format, alignment and asynchronous retention remain native-call obligations. Output storage must be initialized; returned sizes do not enlarge its capacity.

Errors

Returns a construction error if the length exceeds the native count width.

pub fn push_next<T: Extends<Self>>( self, next: &'a mut T, ) -> Result<Self, ConstructionError>

Prepend one registry-compatible node, retaining its exclusive borrow.

The node must have a null p_next and both headers must have canonical tags. Existing links are never traversed and remain written after the borrow ends. Type compatibility does not establish enabled extensions or Vulkan valid usage.

Errors

Returns a construction error for a changed structure tag or already-linked node.
