What is CUID2?
- Secure: It's not possible to guess the next ID.
- Collision resistant: It's extremely unlikely to generate the same ID twice.
- Horizontally scalable: Generate IDs on multiple machines without coordination.
- Offline-compatible: Generate IDs without a network connection.
- URL and name-friendly: No special characters.

Usage
You can generate CUIDs with the following:
from cuid2 import Cuid
CUID_GENERATOR: Cuid = Cuid()
def main():
my_cuid: str = CUID_GENERATOR.generate()
next_cuid: str = CUID_GENERATOR.generate()
