Macro sfsm_proc::derive_transition_into

derive_transition_into!() { /* proc-macro */ }

Derives an a implementation of the into trait for the transition if the target state does not contains any members

derive_transition_into!(Foo, Bar);
// Generates
impl Into<Bar> for Foo {
    fn into(self) -> Bar {
        Bar {}
    }
}

This macro is implemented as a proc macro instead of a derive macro because it needs additional info that is difficult to get into a derive macro in a semantic way.
