AFAIK, it's not the traits that does it but rather the generics.

Rust does make it a lot easier to use generics which is likely why using more traits appears to be the cause of longer build times. I think it's just more that the more traits you have, the more likely you are to stumble over some generic code which ultimately generates more code.

Aah, yes, that sounds more correct, the end result is the same, I failed to remember the correct mechanism that led to it. Thank you for the correction!
