Function tokio::io::stdout

source ·
pub fn stdout() -> Stdout
Expand description

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

The returned handle allows writing to standard out from the within the Tokio runtime.

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.


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

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