我有以下Rust程序(rustc 1.0.0-nightly(44a287e6e 2015-01-08 17:03:40 -0800)):

use std::io::BufferedReader;
use std::io::File;

fn main() {
    let path = Path::new("nc.txt");
    let mut file = BufferedReader::new(File::open(&path));
    let lines: Vec<String> = file.lines().map(|x| x.unwrap()).collect();
    println!("{}", lines[500]);
}

根据http://doc.rust-lang.org/std/io/上的示例,上面是将文件的行拉成字符串向量的方法.我已经投入了第500行的输出.

为了解决Python中的相同任务,我写了以下内容:

#!/usr/local/bin/python3

def main():
    with open('nc.txt', 'r') as nc:
        lines = nc.read().split('\n')
    print("{}".format(lines[500]))

if __name__ == '__main__':
    main()

当我运行编译的Rust并计时时,我得到了这个:

rts@testbed $ time ./test
A declaration of independence by Kosovo will likely bring a similar declaration from Georgia's breakaway Abkhazia region, which Russia could well recognize.

./test  1.09s …
