Expand description

Encoder trait. Each codec ships exactly one impl.

Required Methods§

Source

fn codec(&self) -> Codec

Codec identifier produced by this encoder.

Source

fn encode(&self, values: &[f32]) -> Result<EncodedVector, EncodingError>

Encode values into an EncodedVector.

§Errors

Returns EncodingError::EmptyVector for a zero-dim input, EncodingError::DimensionTooLarge for >65535 dimensions, and EncodingError::NonFinite for any non-finite component.

Source

fn decode(&self, ev: &EncodedVector) -> Result<Vec<f32>, EncodingError>

Decode an EncodedVector back to Vec<f32>.

§Errors

Returns EncodingError::CodecMismatch when the EncodedVector was produced by a different codec, and EncodingError::Malformed when the payload byte count does not match the recorded dimension.
