Struct D3d11VideoCompositorHandle 

pub struct D3d11VideoCompositorHandle { /* private fields */ }

Available on Windows and crate feature d3d11 only.

A cheaply cloneable handle for adding and removing D3d11VideoCompositor inputs — the GPU sibling of crate::elements::VideoCompositorHandle, same shape and behavior.

Implementations

impl D3d11VideoCompositorHandle

pub fn add_source( &self, name: impl Into<String>, layer: VideoLayer, ) -> Result<Option<D3d11VideoCompositorInput>, D3d11VideoCompositorError>

Registers an input and returns its terminal Sink plus independent runtime layer control — see crate::elements::VideoCompositorHandle::add_source’s own docs (identical contract: reusing name replaces the old registration, old sinks/layer handles become harmlessly stale).

pub fn add_layer( &self, name: impl Into<String>, layer: VideoLayer, ) -> Result<Option<D3d11VideoLayerHandle>, D3d11VideoCompositorError>

Registers an input and returns only its layer handle — no Sink at all — for a caller that drives this input’s frames directly via D3d11VideoLayerHandle::set_frame instead of wiring a Pipeline branch into it (e.g. crate::elements::TextLayer). Same replace-on-reuse contract as Self::add_source.

pub fn remove_source(&self, name: &str)

pub fn source_count(&self) -> usize

pub fn add_text_layer( &self, name: impl Into<String>, text_layer: TextLayer, ) -> Result<Option<D3d11TextLayerHandle>, D3d11TextLayerError>

Registers a new text layer and returns a D3d11TextLayerHandle ready for D3d11TextLayerHandle::set_text — the text-specific sibling of Self::add_layer (which stays generic, unaware of text), taking a TextLayer the same way add_source takes a VideoLayer. Always uses this compositor’s own device internally, so unlike a hand-assembled add_layer + separately-supplied device there’s no way to accidentally construct a D3d11TextLayerHandle against the wrong device — the one class of bug a caller-supplied device would allow. Returns None if the compositor has already been dropped, matching Self::add_layer’s own contract.

Trait Implementations

impl Clone for D3d11VideoCompositorHandle
