Function hashAdd

pkg/ingester/client/fnv.go:33–39

hashAdd adds a string to a fnv64a hash value, returning the updated hash. Note this is the same algorithm as Go stdlib `sum64a.Write()`

(h uint64, s string)

// hashAdd adds a string to a fnv64a hash value, returning the updated hash.
// Note this is the same algorithm as Go stdlib `sum64a.Write()`
func hashAdd(h uint64, s string) uint64 {
	for i := 0; i < len(s); i++ {
		h ^= uint64(s[i])
		h *= prime64
	}
	return h
}

// hashAddByte adds a byte to a fnv64a hash value, returning the updated hash.
