NoHashHasher

For an enabled type T, a NoHashHasher<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.

NoHashHasher 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 NoHashHasher is enabled for u8, u16, u32, u64, usize, i8, i16, i32, i64, and isize. Types that should be used with NoHashHasher 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.
