}

The shared trait between all the hashing implementations, which directs the APIs available for appending data and receiving a hash result.

Required methods

`fn hash64(self, data: &[u8]) -> u64`

Convenience function for hashing all data in a single call and receiving a 64bit hash. Results are equivalent to appending the data manually.

`fn hash128(self, data: &[u8]) -> [u64; 2]`

Convenience function for hashing all data in a single call and receiving a 128bit hash. Results are equivalent to appending the data manually.

`fn hash256(self, data: &[u8]) -> [u64; 4]`

Convenience function for hashing all data in a single call and receiving a 256bit hash. Results are equivalent to appending the data manually.

`fn append(&mut self, data: &[u8])`

Adds data to be hashed. If it is important, the performance characteristics of this function differs depending on the amount of data previously hashed and the amount of data to be hashed. For instance, if one appends 50, 1 byte slices then appending the 32nd byte will have a performance outlier as the internal 32 byte block is complete and internally processed.
