Struct CodecImplementation 

pub struct CodecImplementation {
    pub caps: CodecCapabilities,
    pub make_decoder: Option<DecoderFactory>,
    pub make_encoder: Option<EncoderFactory>,
    pub encoder_options_schema: Option<&'static [OptionField]>,
    pub decoder_options_schema: Option<&'static [OptionField]>,
    pub engine_id: Option<&'static str>,
    pub engine_probe: Option<EngineProbeFn>,
}

Internal per-impl record held inside the registry’s id map. Kept distinct from CodecInfo so the id map stays cheap to walk during make_decoder / make_encoder lookups.

Fields

caps: CodecCapabilities

Capability description copied from the originating CodecInfo.

make_decoder: Option<DecoderFactory>

Decoder factory, if this implementation can decode.

make_encoder: Option<EncoderFactory>

Encoder factory, if this implementation can encode.

encoder_options_schema: Option<&'static [OptionField]>

Encoder options schema declared via CodecInfo::encoder_options. None means the encoder accepts no tuning knobs (any non-empty CodecParameters::options will still be rejected by the factory if the encoder calls parse_options — this is purely informational for discovery).

decoder_options_schema: Option<&'static [OptionField]>

Decoder options schema declared via CodecInfo::decoder_options; same semantics as the encoder schema above.

engine_id: Option<&'static str>

HW backend identifier copied verbatim from the originating CodecInfo::engine_id. Some("nvidia"/"vaapi"/...) on HW backends; None on SW codecs. Consumers (CLI info command, pipeline dispatcher, bench loop) read this to group entries by backend without grepping caps.implementation.

engine_probe: Option<EngineProbeFn>

Engine probe function copied verbatim from the originating CodecInfo::engine_probe. Some(fn) on HW backends with a probe wired; None on SW codecs. Consumers call it on demand to enumerate per-device info (crate::engine::HwDeviceInfo).

Trait Implementations

impl Clone for CodecImplementation

fn clone(&self) -> CodecImplementation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
