Function swipl::context::prolog_catch_unwind

pub unsafe fn prolog_catch_unwind<F: FnOnce() -> R + UnwindSafe, R>(
    f: F
) -> PrologResult<R>

Call the given function, converting panics into prolog exceptions.

If the inner function panics, an exception of the form error(rust_error(panic("..the panic message.."))) will be raised, and this function will return Err(PrologError::Exception). Otherwise, This function will return Ok(()).

This is used by various macros to ensure that panics from user code do not propagate into prolog.

Safety

This is only safe to use from an environment from which we can raise a prolog exception.
