Method HDelAll

structure/hash.go:383–416

HDelAll deletes all fields from a hash. It takes a string key 'k' to be deleted from the hash. It returns a boolean indicating the success of the operation and any possible error. Parameters: k: The key of the hash table. Returns: bool: True if the hash was deleted successfully, false otherwis

(key string)

//	bool: True if the hash was deleted successfully, false otherwise.
//	error: An error if occurred during the operation, or nil on success.
func (hs *HashStructure) HDelAll(key string) (bool, error) {
	// Convert the parameters to bytes
	k := stringToBytesWithKey(key)

	// Check the parameters
	if len(k) == 0 {
		return false, _const.ErrKeyIsEmpty
	}

	// Find the hash metadata by the given key
	hashMeta, err := hs.findHashMeta(key, Hash)
	if err != nil {
		return false, err
	}

	// If the counter is 0, return false
	if hashMeta.counter == 0 {
		return false, nil
	}

	// Create a new write batch
	batch := hs.db.NewWriteBatch(config.DefaultWriteBatchOptions)

	// Delete the field from the database
	_ = batch.Delete(k)

	// Commit the write batch
	err = batch.Commit()
	if err != nil {
		return false, err
	}

	return true, nil
}

// HExpire sets a timeout on a hash.
// It takes a string key 'k' and a duration 'ttl' to set the timeout.
