Crate arc_web 

Arc framework runtime.

Holds the reusable web/runtime machinery — Actix middleware, Tera helpers, the event-sourced stack wiring, the websocket transport, and the server bootstrap — behind a builder seam. Applications depend on this crate by version and plug their own aggregate, projectors, and routes in through ArcApp::builder. No concrete domain type lives here: the runtime is generic over arc_core::aggregate::Aggregate.

Structs

AppState

Shared application state accessible by request handlers via web::Data.

ArcApp

Entry point to the framework. Applications register one or more aggregate types, their projectors, and routes, then drive the result with ArcAppBuilder::serve.

ArcAppBuilder

Application builder holding type-erased registrations for every aggregate served by the process. Each registration produces its own typed CommandBus<A> while sharing the configured storage backend.

ProjectorReg

A read-model projector plus the view (table) it maintains. Applications register these against their aggregate so the framework can drive synchronous, read-after-write projections in single-process mode.

Functions

check_app_health

Copies .env.example to .env when no .env file is present.

check_database_health

Verifies database availability for the configured driver. For file-backed drivers (SQLite) this checks the DATABASE_URL file exists and exits with code 1 if missing. Connection-string drivers (Postgres) skip the check.

validate_environment

Fails fast if required environment variables are missing.
