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

Available on unstable only.

Expand description

Prints to the standard error.

Equivalent to the print! macro, except that output goes toio::stderr instead of io::stdout. See print! for example usage.

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

§Panics

Panics if writing to io::stderr fails.

§Examples

use async_std::eprint;

eprint!("Error: Could not complete task").await;
