Struct FrameBuilder 

pub struct FrameBuilder { /* private fields */ }

Builder used for explicit output allocation and writes.

Implementations

impl FrameBuilder

pub fn new( format: FormatDescriptor, width: usize, height: usize, schema: &MetadataSchema, ) -> Result<FrameBuilder, PixelFlowError>

Allocates explicit output buffers for a frame.

pub unsafe fn new_uninit( format: FormatDescriptor, width: usize, height: usize, schema: &MetadataSchema, ) -> Result<FrameBuilder, PixelFlowError>

Allocates explicit output buffers for a frame without zeroing them.

Safety

The caller MUST initialize the underlying buffer before reading from it.

pub fn plane_mut<T>( &mut self, index: usize, ) -> Result<PlaneMut<'_, T>, PixelFlowError>

where T: Sample,

Returns typed mutable plane view.

pub const fn actual_alignment(&self) -> usize

Returns fixed frame allocation alignment.

pub fn finish(self) -> Frame

Finishes builder and returns immutable frame handle.
