MultiReader - a composite reader implementation.

Like std::io::Chain but allows to chain more than two readers together.

Usage

extern crate multi_reader;
use std::env;
use std::io::{BufRead, BufReader};
use std::fs::File;

fn main() {
    let args: Vec<_> = env::args().collect();
    let files = args[1..].iter().map(|f| File::open(f).expect("File not found"));
    let reader = BufReader::new(multi_reader::MultiReader::new(files));
    println!("Total lines count: {}", reader.lines().count());
}

Examples

Run cargo run --example main chained /path/to/file/a /path/to/file/b ....
