macro_rules! eprint {
($($arg:tt)*) => { ... };
}Expand description
Prints to the standard error.
Equivalent to the print! macro, except that output goes to
io::stderr instead of io::stdout. See print! for
example usage.
Use eprint! only for error and progress messages. Use print!
instead for the primary output of your program.
Panics
Panics if writing to io::stderr fails.
Writing to non-blocking stdout can cause an error, which will lead this macro to panic.
Examples
eprint!("Error: Could not complete task");Run
