Struct bytecodec::bytes::Utf8Decoder

pub struct Utf8Decoder<D = RemainingBytesDecoder>(_);

Utf8Decoder decodes Rust strings from a input byte sequence.

Examples

use bytecodec::{Decode, Eos};
use bytecodec::bytes::Utf8Decoder;

let mut decoder = Utf8Decoder::new();

let (_, item) = decoder.decode(b"foo", Eos::new(true)).unwrap();
assert_eq!(item, Some("foo".to_owned()));

Methods

impl Utf8Decoder<RemainingBytesDecoder>

pub fn new() -> Self

Makes a new Utf8Decoder that uses RemainingBytesDecoder as the internal bytes decoder.

impl<D> Utf8Decoder<D> where
    D: Decode<Item = Vec<u8>>, 

pub fn with_bytes_decoder(bytes_decoder: D) -> Self

Makes a new Utf8Decoder with the given bytes decoder.

Trait Implementations

impl<D: Debug> Debug for Utf8Decoder<D>

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

Formats the value using the given formatter.

impl<D: Default> Default for Utf8Decoder<D>

fn default() -> Utf8Decoder<D>

Returns the "default value" for a type.

impl<D> Decode for Utf8Decoder<D> where
    D: Decode<Item = Vec<u8>>, 

type Item = String

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.
