This is because Rust allows blanket implementations to be used inside generic code without them appearing in the trait bound. For example, the get_first_value function can be rewritten to work with any key type T that implements Display and Eq. When this generic code is compiled, Rust would find that there is a blanket implementation of Hash for any type T that implements Display, and use that to compile our generic code. If we later on instantiate the generic type to be u32, the specialized instance would have been forgotten, since it does not appear in the original trait bound.
