uuid.v4()

A randomly generated universally unique identifier (UUID) that relies on random or pseudo-random numbers for uniqueness.

local id = uuid.v4() -- or just calling `uuid()`
print("v4:", id)
-- v4:	1c03ac80-06c8-468a-a3d6-42ef52aa6e57

uuid.v7()

A time-ordered UUID based on Unix timestamps, designed for better performance and database indexing while maintaining high entropy.

local id = uuid.v7()
print("v7:", id)
-- v7:	0195c8f2-a26e-7323-afa0-72eea6ae79cd
