Function std::io::stdout

ⓘImportant traits for Stdout
impl Write for Stdout
pub fn stdout() -> Stdout

Constructs a new handle to the standard output 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 Stdout::lock method.

Examples

Using implicit synchronization:

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

fn main() -> io::Result<()> {
    io::stdout().write(b"hello world")?;

    Ok(())
}

Using explicit synchronization:

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

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

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

    Ok(())
}
