Description:
cuid 0.4
cuid.py
Implementation of https://github.com/ericelliott/cuid in Python.
A cuid is a portable and sequentially-ordered unique identifier designed for
horizontal scalability and speed -- this version is ported from the reference
implementation in Javascript.
NOTE: Particularly if you have security concerns, the cuid standard has been deprecated in favor of cuid2!
Tested on CPython 2.7, 3.6-3.11 as well as PyPy & PyPy3.
Rough benchmarks on my machine (i7-8750H CPU @ 2.20GHz) using setup.py bench
(which times the creation of 1 million cuids):

(Note that timing the creation of fewer IDs changes the way PyPy runs the code, because of JIT warmup --
obviously creating this many IDs takes advantage of the warmed JIT)
For now, this has no dependencies outside the standard library -- in time this may change,
to provide better random numbers and / or performance.
