Many will probably stick with UUIDv4 for years to come, but this looks great

@martinthenth Could you please make ecto an optional dependency? I don’t see why it’s required since not every project that would use your package would really need ecto stuff and so there would be 3 dependencies less (which btw. is half of all deps).
Required: uuidv7 -> rustler_precompiled -> castore
Not required: ecto -> decimal + telemetry
Also one question … Previous comments mentions that it’s just proposal, so I wonder if it’s possible that the output of generate/0 function could change in future?

uuid v5-v8 were accepted in May this year: RFC 9562: Universally Unique IDentifiers (UUIDs) | RFC Editor

Thanks! In that case I would ask to update documentation as I did not found any RFC mention either on hexdocs nor GitHub’s readme file.

Thanks for the suggestion. You’re right that ecto is not required when using it without the Ecto.Type and I’ll add that to the roadmap for v1.0.0. When I find some time to work on that, I’ll also remove the dependency on rustler and make it a full Elixir-based UUID v7 generator. I’ll extend the testing suite to make sure it won’t break anything and remains fully compliant to the spec

In my case I need to find a time when it would not be so hot 
Oh, really? I really liked that your solution is focused on performance. I have already used it and as you mentioned I needed to call Process.sleep(1). Having in mind that besides it I’m doing some metaprogramming it shows how fast the whole code is and I’m really counting on it since in my case performance is what I really need. 
Just for sure making ecto optional is completely different case to rustler and also rustler_precompiled - it’s completely fine and even desired to have them as dependencies having in mind performance results in benchmarks. 
Will definitely wait for 1.0.0 release. Hopefully it would not be so hot as I have some real world use case for fast UUID generation … 
Thank you very much for your work and time. Having such packages is indisputably important and very helpful.
