Partial bytes decoder traits.

Required Methods

fn partial_decode( &self, decoded_regions: &[ByteRange], options: &CodecOptions ) -> Result<Option<Vec<Vec<u8>>>, CodecError>

Partially decode bytes.

Returns None if partial decoding of the input handle returns None.

Errors

Returns CodecError if a codec fails or a byte range is invalid.

Provided Methods

fn partial_decode_concat( &self, decoded_regions: &[ByteRange], options: &CodecOptions ) -> Result<Option<Vec<u8>>, CodecError>

Partially decode bytes and concatenate.

Returns None if partial decoding of the input handle returns None.

Codecs can manually implement this method with a preallocated array to reduce internal allocations.

Errors

Returns CodecError if a codec fails or a byte range is invalid.

fn decode(&self, options: &CodecOptions) -> Result<MaybeBytes, CodecError>

Decode all bytes.

Returns None if partial decoding of the input handle returns None.

Errors

Returns CodecError if a codec fails.
