Crate osom_lib_hashes 

This crate defines various hashing functions, which are ABI stable (as in #[repr(C)]).

Additionally all the hash functions here work in the const context.

The crate is #![no_std].

Notes

In terms of raw performance:

• FxHash is the fastest.
• SipHash and FNV1a_64 are over twice as slow.
• SHA2_256_Portable is obviously the slowest, like 40x slower than FxHash.
• However platform specific implementations of SHA2_256 are actually quite fast. Especially for bigger input these are comparable with SipHash.

So if cryptographic security is not a concern, then FxHash is a valid choice, since it also is quite ok in terms of collision resistance.
