Prints to [stderr][crate::stderr].

Equivalent to the [print!] macro, except that output goes to stderr instead of stdout. See [print!] for example usage.

Use eprint! only for error and progress messages. Use print! instead for the primary output of your program.

NOTE: Not all eprint! calls will be captured in tests like [std::eprint!]

• Capturing will automatically be activated in test binaries
• Otherwise, only when the test feature is enabled

Panics

Panics if writing to stderr fails for any reason except broken pipe.

Writing to non-blocking stdout can cause an error, which will lead this macro to panic.

Examples

#  #[cfg(feature = "auto")] {
use anstream::eprint;

eprint!("Error: Could not complete task");
# }
