This accepts any tags but the decoded values will be discarded.

Methods

impl UnknownFieldDecoder

pub fn new() -> Self

Makes a new UnknownFieldDecoder instance.

Trait Implementations

impl Debug for UnknownFieldDecoder

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Decode for UnknownFieldDecoder

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.

impl FieldDecode for UnknownFieldDecoder

fn start_decoding(&mut self, tag: Tag) -> Result<bool>

Tries to start decoding a field.

impl Default for UnknownFieldDecoder

fn default() -> Self
