Rb_funcall and explicit method cache

ruby-talk
1

I'm implementing some code that calls the same method multiple times
from C. I'd like to cache the method to avoid costly method lookup. Is
this possible?

Something like

    METHOD * m = rb_method_lookup(object, rb_intern("doit"));
    rb_invoke(m, args...)

Is any such thing possible?

Thanks
Samuel

You can use rb_obj_method (just like you would use #method in pure ruby).

I'd measure first that this is your actual bottleneck before you go an optimize a tenth of a percent away.
