## LICENSE

New BSD. See [License
File](https://github.com/timonwong/cyksuid/blob/master/LICENSE).

## Install

`cyksuid` is on the Python Package Index
([PyPI](https://pypi.org/project/cyksuid)):

```bash
pip install cyksuid
```

## Dependencies

`cyksuid` supports Python 3.7+ with a common codebase. It is developed
in Cython, but requires no dependency other than CPython and a C
compiler.

## Sample Usage

### v1 API

```python
from cyksuid import ksuid, parse

uid = ksuid.ksuid()

uid.bytes       # b'\x0f\xd4oB\x81I\xe5\x8d\x95\xb5\xeb\xbc"\xa0\xcd\xfe)N\xe0I'
uid.hex         # '0fd46f428149e58d95b5ebbc22a0cdfe294ee049'
uid.datetime    # datetime.datetime(2022, 10, 12, 13, 12, 34)
uid.timestamp   # 1665580354
uid.encoded     # b'2G2IfS6177qFICE3w10eMjgYu89'

parse(uid.encoded)
```

### v2 API

```python
from cyksuid.v2 import ksuid, parse

uid = ksuid()

uid.bytes       # b'\x0f\xd4oB\x81I\xe5\x8d\x95\xb5\xeb\xbc"\xa0\xcd\xfe)N\xe0I'
uid.hex         # '0fd46f428149e58d95b5ebbc22a0cdfe294ee049'
uid.datetime    # datetime.datetime(2022, 10, 12, 13, 12, 34, tzinfo=datetime.timezone.utc)
uid.timestamp   # 1665580354.0
uid.encoded     # b'2G2IfS6177qFICE3w10eMjgYu89'
str(uid)        # '2G2IfS6177qFICE3w10eMjgYu89'

parse(uid.encoded)
```
