Unlike standard UUIDs, version 7 UUIDs sort chronologically by their creation time, making them useful for databases and systems where insertion order matters. The package provides multiple output formats (bytes, hex, int, str, uuid, or None).\n\nThe implementation allocates the 128 bits as: 36 bits of whole seconds since epoch, 24 bits of fractional seconds (approximately 50ns resolution), 14 bits of sequential counter for repeated calls within the same time tick, and 48 bits of randomness, plus RFC4122-mandated version and variant bits. Generation is faster than uuid.uuid4() when returning integers or strings, though slightly slower when returning UUID objects.","worth_installing":"Yes, if you need time-sortable UUIDs and can accept a dormant package (no updates since 2021-12-29). The implementation is simple, dependency-free, and MIT-licensed. However, verify that RFC4122 version 7 adoption aligns with your infrastructure's UUID support before committing to it as a primary identifier scheme."},"id":"uuid7","links":{"html":"https://skillfed.io/packages/uuid7","md":"https://skillfed.io/packages/uuid7.md","pypi":"https://pypi.org/project/uuid7/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2021-12-29","license_spdx":null,"license_treatment":"permissive","name":"uuid7","python_support":"supports_current","summary":"UUID version 7, generating time-sorted UUIDs with 200ns time resolution and 48 bits of randomness"},"popularity":{"monthly_downloads":14610259,"position":1223,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.1.0"}
