Struct varu64::nb::LengthValueLimitDecoder

pub struct LengthValueLimitDecoder(_, _);

State for decoding a VarU64 followed by that many bytes into a Vec<u8>, erroring if the VarU64 is greater than a limit.

Implementations

impl LengthValueLimitDecoder

pub fn new(limit: u64) -> LengthValueLimitDecoder

Create a new LengthValueLimitDecoder, only accepting values up to length limit.

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

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.
