uuid
Unique identifiers and random tokens (v4 random, v7 time-ordered, plus raw random hex/tokens).
Naming convention: import the module under its bare name (
import "uuid"), reach members with a backslash, and call methods incamelCase:uuid\someMethod.
Methods
v4
A random (version 4) UUID string, e.g. "9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d".
Signature: uuid\v4() -> string - source
Returns: string
v7
A time-ordered (version 7) UUID string; lexically sorts by creation time, which makes it a good ordered run/build id.
Signature: uuid\v7() -> string - source
Returns: string
randomHex
A cryptographically random lowercase hex string of n bytes (2*n characters); errors when n is not positive.
Signature: uuid\randomHex(n) -> string - source
