Struct std::io::Stdout1.0.0 [] [src]

pub struct Stdout { /* fields omitted */ }

A handle to the global standard output stream of the current process.

Each handle shares a global buffer of data to be written to the standard output stream. Access is also synchronized via a lock and explicit control over locking is available via the lock method.

Created by the io::stdout method.


impl Stdout

Important traits for StdoutLock<'a>

Locks this handle to the standard output stream, returning a writable guard.

The lock is released when the returned lock goes out of scope. The returned guard also implements the Write trait for writing data.


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

fn main() -> io::Result<()> {
    let stdout = io::stdout();
    let mut handle = stdout.lock();

    handle.write(b"hello world")?;
