Fields

codec_id: String

Codec identifier.

codec_version: String

Codec version string.

quality: f64

Quality setting used.

file_size: usize

Encoded file size in bytes.

bits_per_pixel: f64

Bits per pixel of the encoded image.

encode_time: Duration

Encoding time.

decode_time: Option<Duration>

Decoding time (if decoder was provided).

metrics: MetricResult

Quality metrics comparing decoded to reference.

perception: Option<PerceptionLevel>

Perception level based on metrics.

cached_path: Option<PathBuf>

Path to cached encoded file (if caching enabled).

codec_params: HashMap<String, String>

Additional codec-specific parameters used.
