Python UUID implementation using Rust's UUID library.This will makeuuid4 function around 10x faster.
This package can be a drop-in replacement to the standard library UUIDwhich implements existing UUID versions like v4 in Rustand also adds draft UUID versions like v6.
Avaialble 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.
Please note that UUID versions 6, 7 and 8 are still in draft RFC.
Usingpip:
or, usingconda:
$ conda install -c conda-forge uuid-utils
>>> 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')In some cases, for example if you are usingDjango, you might needUUID instances to be returnedfrom the standrad-libraryuuid, not a customUUID class.In that case you can use theuuid_utils.compat which comes with a performance penaltyin comparison with theuuid_utils default behaviour, but is still faster than the standard-library.

Benchmark results might vary in different environments, but in most cases the uuid_utils should outperform stdlib uuid.
