Fast, drop-in replacement for Python's uuid module, powered by Rust.
|
|
|
|
Available UUID versions:
|
|
|
|
- `uuid1` - Version 1 UUIDs using a timestamp and monotonic counter.
|
|
- `uuid3` - Version 3 UUIDs based on the MD5 hash of some data.
|
|
- `uuid4` - Version 4 UUIDs with random data.
|
|
- `uuid5` - Version 5 UUIDs based on the SHA1 hash of some data.
|
|
- `uuid6` - Version 6 UUIDs using a timestamp and monotonic counter.
|
|
- `uuid7` - Version 7 UUIDs using a Unix timestamp ordered by time.
|
|
- `uuid8` - Version 8 UUIDs using user-defined data.
|
|
|
|
## Installation
|
|
Using `pip`:
|
|
```shell
|
|
$ pip install uuid-utils
|
|
```
|
|
or, using `conda`:
|
|
|
|
```shell
|
|
$ conda install -c conda-forge uuid-utils
|
|
```
|
|
|
|
## Example
|
|
|
|
```shell
|
|
>>> import uuid_utils as uuid
|
|
|
|
>>> # make a random UUID
|
|
>>> uuid.uuid4()
|
|
UUID('ffe95fcc-b818-4aca-a350-e0a35b9de6ec')
|
|
|
|
>>> # make a random UUID using a Unix timestamp which is time-ordered.
|
|
>>> uuid.uuid7()
|
|
UUID('018afa4a-0d21-7e6c-b857-012bc678552b')
|
|
|
|
>>> # make a UUID using a SHA-1 hash of a namespace UUID and a name
|
|
>>> uuid.uuid5(uuid.NAMESPACE_DNS, 'python.org')
|
|
UUID('886313e1-3b8a-5372-9b90-0c9aee199e5d')
|
|
|
|
>>> # make a UUID using an MD5 hash of a namespace UUID and a name
|
|
>>> uuid.uuid3(uuid.NAMESPACE_DNS, 'python.org')
|
|
UUID('6fa459ea-ee8a-3ca4-894e-db77e160355e')
|
|
```
|
|
|
|
## Compatibility with Python UUID
|
|
|
|
In some cases, for example if you are using `Django`, you might need `UUID` instances to be returned
|
|
from the standard-library `uuid`, not a custom `UUID` class.
|
|
In that case you can use the `uuid_utils.compat` which comes with a performance penalty
|
|
in comparison with the `uuid_utils` default behaviour, but is still faster than the standard-library.
|
|
|
|
```py
|
|
>>> import uuid_utils.compat as uuid
|
|
|
|
>>> # make a random UUID
|
|
>>> uuid.uuid4()
|
|
UUID('ffe95fcc-b818-4aca-a350-e0a35b9de6ec')
|
|
```
