macro_rules! println {
    () => { ... };
    ($($arg:tt)*) => { ... };
}

Available on unstable only.

Expand description

Prints to the standard output, with a newline.

On all platforms, the newline is the LINE FEED character (\n/U+000A) alone (no additional CARRIAGE RETURN (\r/U+000D)).

Use the format! syntax to write data to the standard output. See std::fmt for more information.

Use println! only for the primary output of your program. Useeprintln! instead to print error and progress messages.

§Panics

Panics if writing to io::stdout fails.

§Examples

use async_std::println;

println!().await; // prints just a newline
println!("hello there!").await;
println!("format {} arguments", "some").await;
