Function std::io::stdin

Important traits for Stdin

impl Read for Stdin

pub fn stdin() -> Stdin

Constructs a new handle to the standard input of the current process.

Each handle returned is a reference to a shared global buffer whose access is synchronized via a mutex. If you need more explicit control over locking, see the lock() method.

Examples

Using implicit synchronization:

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

let mut buffer = String::new();
io::stdin().read_to_string(&mut buffer)?;

Using explicit synchronization:

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)?;
