1.19.0[−][src]Macro std::eprintln
Macro for printing to the standard error, with a newline.
Equivalent to the println! macro, except that output goes to
io::stderr instead of io::stdout. See println! for
example usage.
Use eprintln! only for error and progress messages. Use println!
instead for the primary output of your program.
Panics
Panics if writing to io::stderr fails.
Examples
eprintln!("Error: Could not complete task");Run
