While protobuf's type system guarantees structural correctness, it cannot enforce business logic constraints like value ranges, string patterns, or required relationships between fields. This package reads validation annotations embedded in your protobuf schema and applies runtime checks that raise ValidationFailed when a message violates those constraints.\n\nThe package depends on Jinja2, protobuf, and validate-email to generate and execute validators. It supports Python 3.10 through 3.13 and installs with low friction as a pure Python wheel. The repository is archived and abandoned, meaning no new features or security patches are being released, so it is suitable only for stable, self-contained use cases where you can accept the risk of unpatched issues.","worth_installing":"Yes, with conditions. The package solves a real problem\u2014runtime semantic validation of protobuf messages\u2014and has low install friction and no known vulnerabilities. However, the repository is archived and abandoned, so install only if you are comfortable maintaining a frozen dependency or if your validation rules are stable and unlikely to need updates.
