Functions

FromInt

FromInt: func(i: int) -> string

FromInt creates a UUID from an integer.

	DNS:  uuid.FromInt(0x6ba7b810_9dad_11d1_80b4_00c04fd430c8)

MD5

MD5: func(space: string, data: bytes | string) -> string

MD5 generates a version 3 UUID based on the supplied name space and data. Use SHA1 instead if you can.

Parse

Parse: func(s: string) -> string

Parse decodes s into a UUID or returns an error. Both the standard UUID forms of xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx and urn:uuid:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx are decoded as well as the Microsoft encoding {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} and the raw hex encoding: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.

SHA1

SHA1: func(space: string, data: bytes | string) -> string

SHA1 generates a version 5 UUID based on the supplied name space and data.

ToInt

ToInt: func(x: string) -> int

ToInt represents a UUID string as a 128-bit value.

URN

URN: func(x: string) -> string

URN reports the canonical URN of a UUID.

Valid validator

validator form

validator(string)

call form

func(s: string) -> _

Valid ensures that s is a valid UUID which would be accepted by Parse.

Variant

Variant: func(x: string) -> int

Variant reports the UUID variant.

Version

Version: func(x: string) -> int

Version reports the UUID version.
