Trait zamm_yin::graph::value_wrappers::KBValue

pub trait KBValue: Any {
    fn as_any(&self) -> &dyn Any;
}

Wrapper for KB values, because Rust doesn't support upcasting at the moment, and the KB should support referring to external data structures that it doesn't own itself.

This is an implementation of https://stackoverflow.com/a/42057047/257583.

Required methods

fn as_any(&self) -> &dyn Any

Because Rust doesn't support upcasting at the moment, this allows us to manually upcast to Any and then downcast to the desired struct thereafter.
