Struct varu64::nb::LengthValueDecoder

pub struct LengthValueDecoder(_, _);

State for decoding a VarU64 followed by that many bytes into a Vec<u8>.

Implementations

impl LengthValueDecoder

pub fn new() -> LengthValueDecoder

pub fn decode(
    &mut self,
    input: &[u8]
) -> (usize, Option<Result<Vec<u8>, DecodeError>>)

Decode a VarU64 from the input, then reads that many bytes into a Vec<u8>.

Returns how many bytes have been read. A None is returned if more input is needed.
