A Rust library to make your ugly panic messages nicer for the end users.
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.
Code: ```rust use prettypanic::prettypanic;
fn main() { pretty_panic!(/* you would put your handler function here */);
panic!("explicit call to panic!()");
}
Output:
txt
Uh oh!
