Types

type ID

type ID struct {
	// contains filtered or unexported fields
}

ID represents a structure for generating unique identifiers. It uses a combination of hostname, timestamp, and a sequence number to ensure uniqueness across distributed systems.

func NewTraceID

func NewTraceID() *ID

NewTraceID creates and returns a new ID instance. It initializes the ID with the current hostname and timestamp.

Returns:

• *ID: A pointer to the newly created ID instance.

Example:

traceID := NewTraceID()
uniqueIdentifier := traceID.New()

func (*ID) New

func (t *ID) New() string

New generates and returns a new unique identifier.

Returns:

• string: A unique identifier combining the prefix and a sequence number.

Example:

traceID := NewTraceID()
id1 := traceID.New() // e.g., "hostname-timestamp-sequence1"
id2 := traceID.New() // e.g., "hostname-timestamp-sequence2"
