Function nuts::panic_info

pub fn panic_info() -> String

Read some information about currently processing activities. This should be called inside a panic hook.

This function is only available in debug mode as a runtime cost is associated with recording the necessary data at all times. The correct flag for conditional compilation is #[cfg(debug_assertions)].

Example

fn add_nuts_hook() {
#[cfg(debug_assertions)]
let previous_hook = std::panic::take_hook();
    std::panic::set_hook(Box::new(move |panic_info| {
        let nuts_info = nuts::panic_info();
        #[cfg(features = "web-debug")]
        web_sys::console::error_1(&nuts_info.into());
        #[cfg(not(features = "web-debug"))]
        eprintln!("{}", nuts_info);
        previous_hook(panic_info)
    }));
}
