Struct std::old_io::RefReaderUnstable

pub struct RefReader<'a, R: 'a> {
    // some fields omitted
}

A RefReader is a struct implementing Reader which contains a reference to another reader. This is often useful when composing streams.

Examples

fn main() { use std::old_io as io; use std::old_io::ByRefReader; use std::old_io::util::LimitReader; fn process_input<R: Reader>(r: R) {} let mut stream = io::stdin(); // Only allow the function to process at most one kilobyte of input { let stream = LimitReader::new(stream.by_ref(), 1024); process_input(stream); } // 'stream' is still available for use here }

use std::old_io as io;
use std::old_io::ByRefReader;
use std::old_io::util::LimitReader;

fn process_input<R: Reader>(r: R) {}

let mut stream = io::stdin();

// Only allow the function to process at most one kilobyte of input
{
    let stream = LimitReader::new(stream.by_ref(), 1024);
    process_input(stream);
}

// 'stream' is still available for use here
