When calling Rust code from C, it's unsafe to call panic!. Doing so may cause unsafe behavior. But when calling user-defined functions, we sometimes need to enforce these rules.

To use this library, add the following to your Cargo.toml file:

[dependencies]
abort_on_panic = "*"

You can than capture a panic! as follows:

#![feature(phase)]
#[phase(plugin, link)] extern crate abort_on_panic;

pub fn main() {
    let result = abort_on_panic!({
        "value"
    });
    assert_eq!("value", result);

    abort_on_panic!({
        panic!("Uh oh.");
    });
}
