Macro std::eprint 1.19.0[−][src]
macro_rules! eprint { ($($arg:tt)*) => { ... }; }
Macro for printing 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.
