I like generics but I find that it is often best to start out writing a version which is not generic (i.e. explicitly only support usize or something) then make it generic after that version is written. As a side benefit, I find that this forces me to really think about if it should actually be generic or not. One time I was writing a small Datalog engine in Rust and was initially going to make it take in generic atoms. However, I ended up deciding after going through the above process that I could just use u64 identities and just store a one to one map from the actual atoms to u64 and keep the implementation simpler.

I agree with the sentiment that it is very easy to overuse genetics though there are scenarios where they are very useful.
