Usage

Use the crates.io repository; add this to your Cargo.toml along with the rest of your dependencies:

[dependencies]
new_debug_unreachable = "1.0"

In your Rust code, the library name is still debug_unreachable:

use debug_unreachable::debug_unreachable;

fn main() {
    if 0 > 100 {
        // Can't happen!
        unsafe { debug_unreachable!() }
    } else {
        println!("Good, 0 <= 100.");
    }
}
