Function swipl::atom::get_atomable

pub fn get_atomable<F, R>(term: &Term<'_>, func: F) -> PrologResult<R>
where
    F: Fn(Option<&Atomable<'_>>) -> R,

Get an atomable out of a term.

This is very much like get_atom, but instead of retrieving the atom, we retrieve the atom’s name as an &str, wrapped by an Atomable. This means the atom reference count does not have to be manipulated, and it should be slightly faster than first getting the atom and then extracting its name.
