# Macro std::println
1.0.0[−][src]

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

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. Use `eprintln!` instead to print error and progress messages.

# Panics

Panics if writing to `io::stdout` fails.

# Examples

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