# Function tokio::io::stdout [−] [src]

    pub fn stdout() -> Stdout

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.

# 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(())
    }
