Macro std::println1.0.0 [] [src]

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

Macro for printing 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 if writing to io::stdout fails.


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