Struct bytecodec::bytes::BytesEncoder

pub struct BytesEncoder<B> { /* fields omitted */ }

BytesEncoder writes the given bytes into an output byte sequence.

Examples

use bytecodec::{Encode, EncodeBuf, EncodeExt};
use bytecodec::bytes::BytesEncoder;

let mut output = [0; 4];
{
    let mut buf = EncodeBuf::new(&mut output);
    let mut encoder = BytesEncoder::with_item(b"foo").unwrap();
    encoder.encode(&mut buf).unwrap();
    assert!(encoder.is_idle());
    assert_eq!(buf.len(), 1);
}
assert_eq!(&output[..], b"foo\x00");

Methods

impl<B> BytesEncoder<B>

pub fn new() -> Self

Makes a new BytesEncoder instance.

Trait Implementations

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

Formats the value using the given formatter.

impl<B> Default for BytesEncoder<B>

fn default() -> Self

Returns the "default value" for a type.

impl<B: AsRef<[u8]>> Encode for BytesEncoder<B>

type Item = B

The type of items to be encoded.

fn encode(&mut self, buf: &mut EncodeBuf) -> Result<()>

Encodes the current item and writes the encoded bytes to the given buffer as many as possible.

fn start_encoding(&mut self, item: Self::Item) -> Result<()>

Tries to start encoding the given item.

fn requiring_bytes_hint(&self) -> Option<u64>

Returns the number of bytes required to encode all the items in the encoder.

fn is_idle(&self) -> bool
