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. 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");
