Implementations

impl<'a> VideoEncodeRateControlInfoKHR<'a>

pub fn new() -> Self

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

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

Set native field flags without native effects.

pub fn set_rate_control_mode( self, value: VideoEncodeRateControlModeFlagBitsKHR, ) -> Self

Set native field rateControlMode without native effects.

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

Set native count layerCount 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_layers( self, value: &'a [VideoEncodeRateControlLayerInfoKHR<'a>], ) -> Result<Self, ConstructionError>

Borrow pLayers and set checked native count layerCount. 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 set_virtual_buffer_size_in_ms(self, value: u32) -> Self

Set native field virtualBufferSizeInMs without native effects.

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

Set native field initialVirtualBufferSizeInMs without native effects.

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.
