Struct DispatchRuntime 

pub struct DispatchRuntime { /* private fields */ }

Provider + handler registry for one host instance.

Implementations

impl DispatchRuntime

pub fn new( provider: Arc<ServiceProvider>, handler_cache: Arc<HandlerCache>, ) -> DispatchRuntime

pub fn provider(&self) -> &Arc<ServiceProvider>

pub fn handler_cache(&self) -> &Arc<HandlerCache>

pub async fn run<F, R>(&self, f: F) -> R

where F: Future<Output = R>,

Run an async block with this runtime active for the current task.

pub async fn run_in_scope<F, R>(self: &Arc<DispatchRuntime>, f: F) -> R

where F: Future<Output = R>,

Run an async block with a fresh DI scope active.

dispatch_provider() resolves within the scope while the block runs, so a hosted service that does dispatch_provider().get_owned::<DbContext>() gets a context bound to this scope (transitive scoped dependencies included), not one cached on the root provider. The scope is disposed when the block finishes.

Hosted services are started and stopped inside this, which is what makes their scoped dependencies per-run instead of process-wide singletons.
