Struct ServiceInitializerContext

pub struct ServiceInitializerContext { /* private fields */ }

Contains context for service initialization.

ServiceInitializerContext also implements Future and resolves to ServiceHandles once it is signaled to do so.

Implementations

impl ServiceInitializerContext

pub fn register_handle<H>(&self, handle: H)

where H: Any + Send + Sync,

Insert a service handle with the given name

pub fn lazy_service<F, S>(&self, service_fn: F) -> LazyService<F, Self, S>

where F: FnOnce(ServiceHandles) -> S,

Call the given function with the final handles once this future is ready (notify_ready is called).

pub fn spawn_when_ready<F, Fut>(self, f: F) -> JoinHandle<Fut::Output>

where F: FnOnce(ServiceHandles) -> Fut + Send + 'static, Fut: Future + Send + 'static, Fut::Output: Send,

Spawn a task once handles are ready. The resolved handles are passed into this closure.

pub fn spawn_until_shutdown<F, Fut>( self, f: F, ) -> JoinHandle<Option<Fut::Output>>

where F: FnOnce(ServiceHandles) -> Fut + Send + 'static, Fut: Future + Send + 'static, Fut::Output: Send + 'static,

Spawn a task once handles are ready. The resolved handles are passed into this closure. The future returned from the closure is polled on a new task until the shutdown signal is triggered.

pub async fn wait_ready(self) -> ServiceHandles

Wait until the service handle are ready and return them when they are.

pub fn get_shutdown_signal(&self) -> ShutdownSignal

Returns the shutdown signal for this stack

pub fn into_inner(self) -> ServiceHandles

impl Clone for ServiceInitializerContext

fn clone(&self) -> ServiceInitializerContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.
