Struct PresentRegionKHR 

pub struct PresentRegionKHR<'a> {
    pub rectangle_count: u32,
    pub p_rectangles: *const RectLayerKHR,
    /* private fields */
}

Native structure VkPresentRegionKHR.

Khronos reference: VkPresentRegionKHR

Fields

rectangle_count: u32

Native field rectangleCount.

p_rectangles: *const RectLayerKHR

Native field pRectangles.

Implementations

impl<'a> PresentRegionKHR<'a>

pub fn new() -> Self

Construct the record with its default native state.

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

Set native count rectangleCount 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_rectangles( self, value: &'a [RectLayerKHR], ) -> Result<Self, ConstructionError>

Borrow pRectangles and set checked native count rectangleCount. 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.

Trait Implementations

impl<'a> Clone for PresentRegionKHR<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Copy for PresentRegionKHR<'a>

impl<'a> Default for PresentRegionKHR<'a>

fn default() -> Self

Returns the “default value” for a type.
