Macro janetrs::jpanic

macro_rules! jpanic {
    () => { ... };
    ($msg:expr $(,)?) => { ... };
    ($msg:expr, $($arg:tt)+) => { ... };
}

Causes a panic in the Janet side (exception). Differently of the Rust panic! macro, this macro does not terminate the current thread. Instead, it sends a error signal with the passed message where the Janet runtime takes care to properly exit.

Examples

use janetrs::jpanic;
jpanic!();
jpanic!("this is a terrible mistake!");
jpanic!(4); // In simple cases you can use any type that Janet implements From trait
jpanic!("this is a {} {message}", "fancy", message = "message");
