Trait FrameSource 

pub trait FrameSource: Send {
    // Required methods
    fn info(&self) -> &MediaInfo;
    fn frames(&mut self) -> Result<Frames<'_>, SourceError>;

    // Provided method
    fn sparse_frames(
        &mut self,
        wanted: &[bool],
    ) -> Result<Frames<'_>, SourceError> { ... }
}

A recording a run reads, once per pass.

Required Methods

fn info(&self) -> &MediaInfo

fn frames(&mut self) -> Result<Frames<'_>, SourceError>

Starts a read from the first frame.

Provided Methods

fn sparse_frames(&mut self, wanted: &[bool]) -> Result<Frames<'_>, SourceError>

Like FrameSource::frames, but a frame whose entry in wanted is false (or past its end) may come without pixels (an empty rgba), which saves converting it. The default converts every frame.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
