Struct ArcAppBuilder 

pub struct ArcAppBuilder<A: Aggregate + 'static> { /* private fields */ }

Application builder, generic over the domain aggregate A. The concrete A (e.g. an application’s UserAggregate) is supplied by the application crate; the framework never names it.

Implementations

impl<A: Aggregate + 'static> ArcAppBuilder<A>

pub fn register_aggregate(self, projectors: Vec<ProjectorReg>) -> Self

Register the aggregate’s read-model projectors. They are subscribed to the in-process event bus so writes update their views synchronously.

pub fn register_projector( self, projector: impl Projector + 'static, view: impl Into<String>, ) -> Self

Register a single projector (chainable alternative to [register_aggregate]).

pub fn register_routes<F>(self, f: F) -> Self

where F: Fn(&mut ServiceConfig) + Send + Sync + 'static,

Mount the application’s own routes. Framework handlers (static assets, websocket, health) are exported from this crate for the closure to reference; the application owns which routes it mounts.

pub fn snapshot_policy(self, policy: Option<SnapshotPolicy>) -> Self

Snapshot policy for the aggregate’s command bus (e.g. every N events).

pub async fn serve(self, app_url: String, app_port: u16) -> Result<()>

Boot the HTTP server with the configured aggregate, projectors, and routes. Equivalent to the old commands::serve::run, now generic.
