PVQ Extension

Extension framework for PVQ with declarative interfaces, metadata generation, execution, and permissions.

What it provides

• Declarative extension traits and implementations via macros
• Generated dispatch and metadata for extensions
• Execution wrapper to run PVQ programs against your extensions
• Pluggable permission controller (allow‑all by default)

Typical use

1. Declare an extension trait and implement it for your runtime.
2. Generate an extensions module (via the macros) and expose its metadata().
3. Initialize ExtensionsExecutor with your generated extensions and an invocation source.
4. Optionally implement a custom PermissionController.

Metadata

• A portable type registry plus per‑extension function signatures (names, inputs, output). Useful to serve from your runtime’s metadata().
