EngineConfig

Struct EngineConfig 

Source
pub struct EngineConfig {
    pub storage: NativeStorage,
    pub http: NativeHttp,
    pub uploader: SharedFileUploader,
    pub event_sink: NativeEventSink,
    pub metrics: Arc<dyn AsyncMetricSink>,
    pub max_http_inflight: usize,
}
Expand description

事件泵配置(native 具体 ports 聚合)。

装配后由 run_engine_loop / run_engine_loop_with_transports 转成 host 的 EngineDeps(注入 NativeClock),调泛型壳 helix_driver_host::engine::run_engine_loop。

Fields§

§storage: NativeStorage§http: NativeHttp§uploader: SharedFileUploader§event_sink: NativeEventSink§metrics: Arc<dyn AsyncMetricSink>

Engine 热路径指标 sink;composition root 应与 HTTP/WS/Storage/Event 共用同一 Arc。

§max_http_inflight: usize

Http effect 并发上限(Http BoundedSpawner 的 worker 数 N)。

冷启动时 core 一步可吐 N 条 Effect::Http;若全部齐发会瞬间打满底层连接 (reqwest pool 不限制新连接并发)。此字段 = Http/HttpFire BoundedSpawner 的常驻 worker 数:第 N+1 条请求在有界队列里等 worker,不并发齐发。host(ambient API 合法落点) 读 env 注入;建议默认 8。0 会被 .max(1) 兜底为 1。
