rainier-support

The primitives every other Rainier crate shares, and nothing else. It sits at the bottom of the dependency graph and depends on no other Rainier crate, which is what lets the components above it stay independent of each other.

• [Error] / [Result] — one error type, carrying the status and the structured details the HTTP layer needs to render any failure.
• [Extensions] — the type-keyed bag behind request attributes and container bindings.
• str — the inflection vocabulary resource routing and the code generators are written against.
• [Setting] / [setting_enum!] — a closed set of config values, so a driver name is an enum rather than a string nobody validates.
• [BoxFuture] — the boxed future the framework's dyn-safe async traits return.
