Struct tokio::io::Stdout

source · []
pub struct Stdout { /* private fields */ }
Expand description

A handle to the standard output stream of a process.

Concurrent writes to stdout must be executed with care: Only individual writes to this AsyncWrite are guaranteed to be intact. In particular you should be aware that writes using write_all are not guaranteed to occur as a single write, so multiple threads writing data with write_all may result in interleaved output.

Created by the stdout function.

Examples

use tokio::io::{self, AsyncWriteExt};

#[tokio::main]
async fn main() -> io::Result<()> {
    let mut stdout = io::stdout();
    stdout.write_all(b"Hello world!").await?;
    Ok(())
}
