Method Size

structure/hash.go:1327–1359

Size returns the size of a field in the hash as a formatted string. It takes a string key 'k' and one or more fields 'f' (optional). It returns a formatted string indicating the size of the field and any possible error. Parameters: k: The key of the hash table. f: The field(s) whose size needs t

(key string)

//	string: A formatted string indicating the size of the field.
//	error: An error if occurred during the operation, or nil on success.

	keysAndValues, err := hs.HGetAllFieldAndValue(key)
	if err != nil {
		return "", err
	}

	var sizeInBytes int

	// Calculate the size
	for f, v := range keysAndValues {
		sizeInBytes += len(f) + len(v.(string))
	}

	// Convert bytes to corresponding units (KB, MB...)
