Trait Implementations

impl FrameProvider for FramesWithText<'_>

fn texture_for( &self, source: &SourceId, time: MediaTime, ) -> Option<SourceView<'_>>

Returns a texture for source at the requested source timestamp.

fn pending_source_work( &self, source: &SourceId, time: MediaTime, ) -> Option<&PendingSourceWork>

Returns presentation work that has not yet been submitted for this physical source texture. The default covers already-ready textures.

fn source_key( &self, source: &SourceId, time: MediaTime, ) -> Option<RenderCacheKey>

A key for the texture Self::texture_for returns, promising its pixels depend on nothing outside the key (content, frame, decode and conversion). Keyed sources let drawn results be reused (alpha2_render::Renderer::set_result_cache_budget); the default None disables reuse.

fn text(&self, key: u64) -> Option<TextTexture<'_>>

Returns the prepared text crate::text_key names. With the default (none), a frame showing text fails with RenderError::MissingText.

fn layout(&self, key: u128) -> Option<Arc<PreparedLayout>>

Returns the prepared layout crate::layout_key names. With the default (none), a frame showing a layout fails with RenderError::MissingText.
