It includes CachedProperty (which recomputes when tracked attributes change), Lazy (which computes once and stays cached until manually deleted), and cached methods. Values are stored in _v_ volatile attributes, making them especially useful for persistent object frameworks where volatile storage is a standard pattern.\n\nThe package is a lightweight, dependency-minimal tool for avoiding redundant computation in classes where properties depend on instance state. It's designed for scenarios where you need fine-grained control over when a cached value is discarded\u2014either automatically when dependencies shift, or manually when needed. It supports both decorator and functional syntax for backwards compatibility.","worth_installing":"Yes, if you need dependency-aware property caching in a persistent object context or are already in the Zope ecosystem. The package is stable, has no known vulnerabilities, and installs with minimal friction. However, the aging maintenance status (no release in 336 days) and unclear license treatment warrant a review before adopting in new projects outside Zope\u2014for simpler caching, functools.cached_property may suffice."},"id":"zope-cachedescriptors","links":{"html":"https://skillfed.io/packages/zope-cachedescriptors","md":"https://skillfed.io/packages/zope-cachedescriptors.md","pypi":"https://pypi.org/project/zope-cachedescriptors/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-09-12","license_spdx":null,"license_treatment":"unclear","name":"zope.cachedescriptors","python_support":"supports_current","summary":"Method and property caching decorators"},"popularity":{"monthly_downloads":155376,"position":10817,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"6.0"}
