Function std::io::stdout
pub fn stdout() -> StdoutⓘNotable traits for Stdoutimpl Write for Stdoutimpl Write for &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.
Note: Windows Portability Consideration
When operating in a console, the Windows implementation of this stream does not support non-UTF-8 byte sequences. Attempting to write bytes that are not valid UTF-8 will return an error.
Examples
Using implicit synchronization:
use std::io::{self, Write}; fn main() -> io::Result<()> { io::stdout().write_all(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_all(b"hello world")?; Ok(()) }
