Trait spaik::subrs::Subr

pub unsafe trait Subr: CloneSubr {
    fn call(&mut self, vm: &mut R8VM<'_>, args: &[PV]) -> Result<PV, Error>;
    fn name(&self) -> &'static str;
}

SAFETY: The call method may be passed an arg reference into the, vm stack (which it gets a mutable reference to.) The call method may not access args after mutating vm.

    This invariant is ensured by the lispy proc-macro, which you
    should use instead of implementing Subr yourself.
