2026-07-10: Hooks, extension traits, and tiny contextsA Rust pattern for keeping analysis contexts small without giving up convenient method calls.
While building
c-rusted-rs, I found myself calling some context helpers "hooks". In hindsight, they were really extension traits layered over a tiny typemap-backed analysis context.The pattern is simple: keep the core context boring, then add opt-in capabilities such as cached analyses through trait methods. It is not novel, but it made the checker dependencies local, readable, and easier to compose.
