Struct bytecodec::StartDecoderChain

pub struct StartDecoderChain;

An object for starting a chain of decoders.

Examples

use bytecodec::{Decode, DecodeExt, StartDecoderChain};
use bytecodec::fixnum::U8Decoder;
use bytecodec::io::IoDecodeExt;

let mut decoder = StartDecoderChain
    .chain(U8Decoder::new())
    .chain(U8Decoder::new())
    .chain(U8Decoder::new());

let mut input = &b"foobar"[..];

let item = decoder.decode_exact(&mut input).unwrap();
assert_eq!(item, (b'f', b'o', b'o'));

let item = decoder.decode_exact(&mut input).unwrap();
assert_eq!(item, (b'b', b'a', b'r'));

Methods

impl StartDecoderChain

pub fn chain<D: Decode>(&self, decoder: D) -> DecoderChain<Self, D, ()>

Starts decoders chain.

Trait Implementations

impl Debug for StartDecoderChain

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

Formats the value using the given formatter.

impl Decode for StartDecoderChain

type Item = ()

The type of items to be decoded.

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

Consumes the given buffer (a part of a byte sequence), and decodes an item from it.

fn has_terminated(&self) -> bool

Returns true if the decoder cannot decode items anymore, otherwise false.

fn requiring_bytes(&self) -> ByteCount

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