# 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*.
