Struct SliceSink 

pub struct SliceSink<'a> { /* private fields */ }

A cursor over a caller buffer.

No allocation; reports remaining; a put that does not fit writes nothing. Debug prints the lengths only, never the bytes.

Examples

use parse_net::{Sink, SliceSink};

let mut buf = [0u8; 8];
let mut out = SliceSink::new(&mut buf);
out.put(b"gzip")?;
assert_eq!(out.written(), b"gzip");
assert_eq!(out.remaining(), Some(4));
out.clear();
assert!(out.is_empty());

Implementations

impl<'a> SliceSink<'a>

pub fn new(buf: &'a mut [u8]) -> Self

A sink that writes into buf, starting at its first byte.

pub fn written(&self) -> &[u8]

The bytes written so far.

pub fn len(&self) -> usize

The number of bytes written so far.

pub fn is_empty(&self) -> bool

Whether nothing has been written.

pub fn clear(&mut self)

Forgets what was written; the buffer is reused from its start.

Trait Implementations

impl Debug for SliceSink<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Sink for SliceSink<'_>

fn put(&mut self, bytes: &[u8]) -> Result<(), Full>

Appends all of bytes, or fails with Full and appends nothing.

fn remaining(&self) -> Option<usize>

How many more bytes fit, when the sink knows; None otherwise.
