Question 1

How to generate a random UUID version 4 with okeuday/uuid?

Accepted Answer

First, initialize randomness by calling quickrand:seed/0, then use uuid:new/1 or similar functions. This ensures secure random generation as per the library's design, with details in the usage section.

Question 2

okeuday/uuid vs erlang-uuid: which should I use?

Accepted Answer

okeuday/uuid is better for distributed Erlang systems due to its integration with process and node info, while erlang-uuid might be simpler but less feature-rich. Consider your need for RFC compliance and distributed optimizations.

Question 3

Does okeuday/uuid support the new UUID version 7?

Accepted Answer

Yes, it fully supports UUID version 7 as specified in RFC 9562. However, note that version 7 has less time precision compared to versions 1 and 6, as mentioned in the README.

Question 4

What dependencies does okeuday/uuid have?

Accepted Answer

It depends on the quickrand library for randomness and requires Erlang version R16B01 or higher. Ensure these are installed and configured correctly for proper functionality.

Question 5

How to use okeuday/uuid in a distributed Erlang application?

Accepted Answer

Use version 1 or 6 UUIDs which include Erlang pid and node information. Initialize quickrand as needed, and follow the usage examples for generating UUIDs optimized for distributed tracking.

Question 6

Is okeuday/uuid compliant with the latest UUID standards?

Accepted Answer

Yes, it is compliant with RFC 9562, which replaces RFC 4122, and supports all standard UUID versions including the newer ones like version 7 and 8, as detailed in the README.
