Required methods

fn decode_quads<S: DecodeQuadSink<Self>>(
    control_bytes: &[u8],
    encoded_nums: &[u8],
    max_control_bytes_to_decode: usize,
    nums_already_decoded: usize,
    sink: &mut S
) -> (usize, usize)

Decode encoded numbers in complete quads.

Only control bytes with 4 corresponding encoded numbers will be provided as input (i.e. no trailing partial quad).

control_bytes are the control bytes that correspond to encoded_nums.

max_control_bytes_to_decode may be greater than the number of control bytes remaining, in which case only the remaining control bytes will be decoded.

Implementations may decode at most max_control_bytes_to_decode control bytes, but may decode fewer.

nums_already_decoded is the number of numbers that have already been decoded in the DecodeCursor.decode invocation.

Returns a tuple of the number of numbers decoded (always a multiple of 4; at most 4 * max_control_bytes_to_decode) and the number of bytes read from encoded_nums.
