macro_rules! println {
() => { ... };
($($arg:tt)*) => { ... };
}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)).
This macro uses the same syntax as format!, but writes to the standard output instead.
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");Run
