Struct tokio::io::Stdout [−][src]
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(()) }
