pretty-panic

A Rust library to make your ugly panic messages nicer for the end users.

What is it?

pretty-panic is a small library that wraps around std::panic::set_hook, allowing you to set your own panic handler functions. It provides a default handler, which just prints a nicer panic message.

How to use?

Code:

use pretty_panic::pretty_panic;

fn main() {
    pretty_panic!(/* you would put your handler function here */);

    panic!("explicit call to panic!()");
}

Output:

Uh oh!

The program experienced a fatal error, and has panicked. Recommend you contact one
