std::io::Stdin

Locks this handle to the standard input stream, returning a readable guard.

The lock is released when the returned lock goes out of scope. The returned guard also implements the Read and BufRead traits for accessing the underlying data.

Examples

use std::io::{self, Read};

let mut buffer = String::new();
let stdin = io::stdin();
let mut handle = stdin.lock();

handle.read_to_string(&mut buffer)?;

Locks this handle and reads a line of input into the specified buffer.

For detailed semantics of this method, see the documentation on BufRead::read_line.

Examples

use std::io;

let mut input = String::new();
match io::stdin().read_line(&mut input) {
    Ok(n) => {
        println!("{} bytes read", n);
        println!("{}", input);
    }
    Err(error) => println!("error: {}", error),
}

You can run the example one of two ways:

• Pipe some text to it, e.g. printf foo | path/to/executable
• Give it text interactively by running the executable directly, in which case it will wait for the Enter key to be pressed before continuing
