Implementations§

Source §

impl<'a> PipelineViewportStateCreateInfo<'a>

Source

pub fn new() -> Self

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

Source

pub fn set_flags(self, value: PipelineViewportStateCreateFlags) -> Self

Set native field flags without native effects.

Source

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

Set native count viewportCount 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.

Source

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

Borrow pViewports and set checked native count viewportCount. 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.

Source

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

Set native count scissorCount 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.

Source

pub fn set_scissors( self, value: &'a [Rect2D], ) -> Result<Self, ConstructionError>

Borrow pScissors and set checked native count scissorCount. 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.

Source

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.
