Functions

func CloneMarshal

func CloneMarshal(m interface{}, s interface{}) error

Uses json.Marshal and json.Unmarshal to copy from one object to another. Excellent way to turn a JSON Object into a struct, or vice-versa.

This makes its changes in-place, so always pass in the pointer to the struct object you're trying to fill.

func HashObject

func HashObject(object interface{}) (string, error)

Serialize an object to compact, deterministic JSON (no whitespace, fields in struct order or alphabetical), then take the SHA1 of that, and return the hex digest.

This is the algorithm we use for hashing events, topics, etc.
