Struct bytecodec::null::NullDecoder

pub struct NullDecoder;

Null decoder.

NullDecoder consumes no bytes and returns Ok(()) when finish_decoding method is called.

Trait Implementations

impl Debug for NullDecoder

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for NullDecoder

fn default() -> NullDecoder

Returns the "default value" for a type.

impl Decode for NullDecoder

type Item = ()

The type of items to be decoded.

fn decode(&mut self, _buf: &[u8], _eos: Eos) -> Result<usize>

Consumes the given buffer (a part of a byte sequence), and proceeds the decoding process.

fn finish_decoding(&mut self) -> Result<Self::Item>

Finishes the current decoding process and returns the decoded item.

fn is_idle(&self) -> bool

Returns true if there are no items to be decoded by the decoder at the next invocation of decode method, otherwise false.

fn requiring_bytes(&self) -> ByteCount

Returns the lower bound of the number of bytes needed to decode the next item.
