println!() { /* proc-macro */ }
Expand description
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");
