Struct bytecodec::value::DecodedValue

pub struct DecodedValue<T>(_);

DecodedValue represents an already decoded item.

It does not consume any bytes, and returns the given item when decode() was first called.

Examples

use bytecodec::{Decode, Eos};
use bytecodec::value::DecodedValue;

let mut decoder = DecodedValue::new(10);

let (size, item) = decoder.decode(b"foo", Eos::new(false)).unwrap();
assert_eq!(item, Some(10));
assert_eq!(size, 0);

Methods

impl<T> DecodedValue<T>

pub fn new(value: T) -> Self

Makes a new DecodedValue instance.

Trait Implementations

impl<T: Debug> Debug for DecodedValue<T>

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

Formats the value using the given formatter.

impl<T> Decode for DecodedValue<T>

type Item = T

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 requiring_bytes(&self) -> ByteCount

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