Method Keys

structure/hash.go:1162–1197

Keys returns a list of all field names in the hash stored at the specified key. It takes no parameters and returns a slice of strings representing the field names and any possible error. Returns: []string: A list of field names in the hash. error: An error if occurred during the operation, or nil

(regx string)

// []string: A list of field names in the hash.
// error: An error if occurred during the operation, or nil on success.

	toRegexp := convertToRegexp(regx)
	compile, err := regexp.Compile(toRegexp)
	if err != nil {
		return nil, err
	}
	// Get all the keys from the database
	byteKeys := hs.db.GetListKeys()

	// Create a new slice of strings
	keys := make([]string, 0)

	for _, key := range byteKeys {
