To see why this overlapping implementation is so problematic, let's look at how the Hash trait is used inside a HashMap. The HashMap's methods, like get, use the Hash trait to compute a hash value for the key, which determines the bucket where the value is stored. For the algorithm to work correctly, the exact same hash function must be used every single time. Now, what happens if we have a situation where both our blanket implementation and a specialized implementation for a type like u32 are available? We might be tempted to say we will always choose the more specialized implementation, but that approach doesn't always work.
