Struct holochain::prelude::dependencies::kitsune_p2p_types::dependencies::lair_keystore_api::dependencies::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(())
}
