Struct std::old_io::BufReaderUnstable

pub struct BufReader<'a> {
    // some fields omitted
}

Reads from a fixed-size byte slice

Example

fn main() { #![allow(unused_must_use)] use std::old_io::BufReader; let buf = [0, 1, 2, 3]; let mut r = BufReader::new(&buf); assert_eq!(r.read_to_end().unwrap(), vec![0, 1, 2, 3]); }

use std::old_io::BufReader;

let buf = [0, 1, 2, 3];
let mut r = BufReader::new(&buf);

assert_eq!(r.read_to_end().unwrap(), vec![0, 1, 2, 3]);

Methods

impl<'a> BufReader<'a>

fn new(buf: &'a [u8]) -> BufReader<'a>

Creates a new buffered reader which will read the specified buffer

fn eof(&self) -> bool

Tests whether this reader has read all bytes in its buffer.

If true, then this will no longer return bytes from read.
