Fireflake: A snowflake id generator in Mojo

Hi all! I've written a new library that generates Snowflake IDs. Quoting Wikipedia: Snowflake ID:

Snowflake IDs, or snowflakes, are a form of unique identifier used in distributed computing. The format was created by Twitter (now X) and is used for the IDs of tweets.[1] It is popularly believed that every snowflake has a unique structure, so they took the name "snowflake ID". The format has been adopted by other companies, including Discord and Instagram. The Mastodon social network uses a modified version.

:github: Repository - https://github.com/sazid/fireflake I've yet to write tests for this, any suggestions or improvements are welcome!

How to prevent compilation when parametric conditions fail?

struct Test[bits_count: Int64 = 10]:
  @parameter
  if bits_count < 0 or bits_count > 10:
      raise Error("Invalid number of bits count.")

struct Test[bits_count: Int64 = 10]:
  @parameter
  if bits_count < 0 or bits_count > 10:
      raise Error("Invalid number of bits count.")

With the above code, I can see that the error is being raised at runtime. Is it possible to stop the compilation with an error message when the parametric condition fails?

Is there any mutex available in the stdlibs?

Searched for mutex in the docs and it looks like it's not available yet. Is there a way I can atomically perform multiple ops or do the following with the atomic package? I want to perform an increment on an int, followed by a modulo which should round the number back to 0 after a certain limit and return the value.

How to get unix timestamp?

Hi, is there currently currently any API to get the unix timestamp (since unix epoch)? I read the docs for time.now() and it seems it only measures the time from the system boot.
