Functions

func HashAny

func HashAny(value any, hasher Hasher) uint64

HashAny hashes an arbitrary Go value (the result of json.Unmarshal) in a canonical way using the provided hasher. It returns a 64-bit non-cryptographic hash.

func HashJSON

func HashJSON(input []byte, hasher Hasher) (uint64, error)

HashJSON takes a blob of JSON, unmarshals it, and returns a 64-bit hash using the provided hasher. If there's an error unmarshaling, it returns 0 and the error.

Types

type Hasher

type Hasher interface {
	hash.Hash
	Sum64() uint64
}

Hasher is an interface that wraps a Sum64 method. Any hash implementation that implements Sum64 can be used with HashAny.
