This package provides RFC 4122 compliant UUIDs. It will generate the following:
- Version 1: based on timestamp and MAC address
- Version 3: based on MD5 hash
- Version 4: based on crytographically secure random numbers
- Version 5: based on SHA-1 hash
Functions NewV1, NewV3, NewV4, NewV5, New, NewHex and ParseUUID() for generating versions 3, 4 and 5 UUIDs are as specified in RFC 4122.
Go 1.2 and tip supported.
- Varient type bits are now set correctly
- Varient type can now be retrieved more efficiently
- New tests for variant setting to confirm correctness
- New tests added to confirm proper version setting
- Type UUID change to UUIDArray for V3-5 UUIDS and UUIDStruct added for V1 UUIDs ** These implement the BinaryMarshaller and BinaryUnmarshaller interfaces
- New was added to create a base UUID from a []byte slice - this uses UUIDArray
- ParseHex was renamed to ParseUUID
- NewHex now performs unsafe creation of UUID from a hex string
- NewV3 and NewV5 now take anything that implements the Stringer interface
- V1 UUIDs can now be created
- The printing format can be changed
