Variables ¶
var ErrInvalidHex = errors.New("the provided hex string is not a valid ObjectID")
ErrInvalidHex indicates that a hex string cannot be converted to an ObjectID.
Functions ¶
func GetOutboundIP ¶
func GetOutboundIP() string
GetOutboundIP Get preferred outbound ip of this machine
func MergeStructByMarshal ¶
func MergeStructByMarshal(a, b interface{}) (err error)
MergeStructByMarshal merge b to a by json.Marshal 0. a & b should be pointer 1. json tag: omitempty is necessary for every `no-zero` attr 2. The performance of this method is not very high for lagre struct
Types ¶
type ObjectID ¶
type ObjectID [12]byte
ObjectID is the BSON ObjectID type.
var NilObjectID ObjectID
NilObjectID is the zero value for ObjectID.
func NewObjectIDFromTimestamp ¶
NewObjectIDFromTimestamp generates a new ObjectID based on the given time.
func ObjectIDFromHex ¶
ObjectIDFromHex creates a new ObjectID from a hex string. It returns an error if the hex string is not a valid ObjectID.
func (ObjectID) MarshalJSON ¶
MarshalJSON returns the ObjectID as a string
func (*ObjectID) UnmarshalJSON ¶
UnmarshalJSON populates the byte slice with the ObjectID. If the byte slice is 24 bytes long, it will be populated with the hex representation of the ObjectID. If the byte slice is twelve bytes long, it will be populated with the BSON representation of the ObjectID. This method also accepts empty strings and decodes them as NilObjectID. For any other inputs, an error will be returned.
