Trait Implementations

impl AppFactory for Factory

type App = ServerApp

The concrete application this factory produces.

fn empty(&self) -> ServerApp

Construct an empty application. Used by all paths that need a clean state: primary startup, replication snapshot receive, journal replay from genesis.

fn prefault(&self, app: &mut ServerApp)

Pre-allocate internal collections for a known bulk-seed workload. Called once on the primary startup path before seeding begins, so the seed phase doesn’t hit allocation stalls as collections grow.

fn apply_operator_policy(&self, app: &mut ServerApp)

Reapply operator-controlled policy (rate limits, caps, …) to an existing app. The policy is NOT journaled — primary and replica must apply matching values independently — so this is called after every snapshot restore (which reconstructs state but not policy) and after every replica reconnect that reuses an existing pipeline. Default impl is a no-op for applications that have no operator policy.

fn seed_events(&self) -> Vec<TradingEvent>

Yield the bulk-seed events the runtime should journal at startup. Called once on a fresh primary (empty journal, no snapshot); replicas receive the same events through standard journal replay and never call this themselves. Default impl returns an empty Vec for applications that don’t bulk-seed.

impl Clone for Factory

fn clone(&self) -> Factory

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Factory

impl Debug for Factory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
