integer-hasher
For an enabled type T, a IntHasher<T> implements std::hash::Hasher and
uses the value set by one of the write_{u8, u16, u32, u64, usize, i8, i16, i32, i64, isize} methods as its hash output.
IntHasher does not implement any hashing algorithm and can only be used
with types which can be mapped directly to a numeric value. Out of the box
IntHasher is enabled for u8, u16, u32, u64, usize, i8, i16,
i32, i64, and isize. Types that should be used with IntHasher need
to implement [IsEnabled] and by doing so assert that their Hash impl invokes
only one of the Hasher::write_{u8, u16, u32, u64, usize, i8, i16, i32, i64, isize} methods exactly once.
Note that for just like fxhash and other stable hashers, there are some performance drawback according to this blob.
