Functions

func ComputeHash

func ComputeHash(obj interface{}) string

ComputeHash computes hash value of a interface

func DeepHashObject

func DeepHashObject(hasher hash.Hash, objectToWrite interface{})

DeepHashObject writes specified object to hash using the spew library which follows pointers and prints actual values of the nested objects ensuring the hash does not change when a pointer changes.

func HashFolder

func HashFolder(ctx context.Context, folder string, filters ...HashFolderFilter) (hash string, err error)

HashFolder generates a hash for the folder

func HashSHA256

func HashSHA256(secretKey string, value []byte) (string, error)

HashSHA256 will generate a hash value using SHA-256.

Types

type HashFolderFilter

type HashFolderFilter func(context context.Context, path string, d fs.DirEntry) bool

func IgnoreFilesFilter

func IgnoreFilesFilter(patterns ...string) HashFolderFilter
