Struct std::old_io::MemReaderUnstable

pub struct MemReader {
    // some fields omitted
}

Reads from an owned byte vector

Example

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

use std::old_io::MemReader;

let mut r = MemReader::new(vec!(0, 1, 2));

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

Methods

impl MemReader

fn new(buf: Vec<u8>) -> MemReader

Creates a new MemReader which will read the buffer given. The buffer can be re-acquired through unwrap

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.

fn get_ref<'a>(&'a self) -> &'a [u8]

Acquires an immutable reference to the underlying buffer of this MemReader.

No method is exposed for acquiring a mutable reference to the buffer because it could corrupt the state of this MemReader.

fn into_inner(self) -> Vec<u8>

Unwraps this MemReader, returning the underlying buffer
