Trait Decoder 

pub trait Decoder {
    // Required methods
    fn streams(&self) -> &[StreamInfo];
    fn flush(&mut self) -> Result<(), DecodeError>;
    fn seek(
        &mut self,
        request: DecodeRequest,
        cancel: &CancelToken,
    ) -> Result<DecodeResult, DecodeError>;
    fn decode_next(
        &mut self,
        cancel: &CancelToken,
    ) -> Result<DecodeEvent, DecodeError>;
}

Stateful media decoder implemented by a platform binding.

Required Methods

fn streams(&self) -> &[StreamInfo]

Returns deterministic stream metadata and stream selection.

fn flush(&mut self) -> Result<(), DecodeError>

Flushes queued packets and frames without changing stream selection.

Errors

Returns a platform-neutral adapter failure when flushing fails.

fn seek( &mut self, request: DecodeRequest, cancel: &CancelToken, ) -> Result<DecodeResult, DecodeError>

Seeks and returns what is presented at the request’s time.

For video this is the last frame at or before the time plus the stream’s alpha2_time::presentation_slack, which absorbs timestamp rounding. Finding it decodes the following frame, which the next Self::decode_next returns. Times before the first frame return the first, times after the last return the last, and a stream without frames is DecodeError::OutOfRange. For audio it is the block holding the time’s sample.

Errors

Returns cancellation, range, unsupported-media, or adapter failures.

fn decode_next( &mut self, cancel: &CancelToken, ) -> Result<DecodeEvent, DecodeError>

Advances packet draining by one observable event.

Errors

Returns cancellation, unsupported-media, or adapter failures.

Dyn Compatibility

This trait is dyn compatible.

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