Trait prisma::encoding::TranscodableColor

pub trait TranscodableColor: Color + EncodableColor {
    type IntermediateColor;
    fn encode_color<Encoder>(self, enc: &Encoder) -> Self
    where
        Encoder: ChannelEncoder;
    fn decode_color<Decoder>(self, dec: &Decoder) -> Self
    where
        Decoder: ChannelDecoder;
}

A color that can have its encoding changed

Because of the non-linear nature of encodings, only Rgb can have its encoding changed. The other device-dependent colors can come from an encoding, and may be stored in EncodedColor, but they must go through Rgb for that encoding to change.
