Unless you have a specific reason otherwise, you probably either want the random v4 or the time-based v1 or v7 versions.

Currently this library only works on the Erlang target as the JavaScript target does not yet support non-byte aligned bit arrays.

Further documentation can be found at https://hexdocs.pm/youid.

Many thanks to Gregggreg for the original version of this library.
