WebI made a crate stable-hash which will give you a collision-resitant structured hash that is deterministic and stable across runs, compilers, std_lib changes, versions, etc. Interestingly, this hash is also backward compatible - meaning if you add new fields to your struct and those fields take the default values you will get the same hash out!

A hash function takes a key as an input, which is associated with a datum or record and used to identify it to the data storage and retrieval application. The keys may be fixed length, like an integer, or variable length, like a name. In some cases, the key is the datum itself. The output is a hash code used … See more A hash function is any function that can be used to map data of arbitrary size to fixed-size values, though there are some hash functions that support variable length output. The values returned by a hash function are called … See more Hash functions are used in conjunction with hash tables to store and retrieve data items or data records.
