Struct tari_service_framework::ServiceInitializerContext

pub struct ServiceInitializerContext { /* fields omitted */ }

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 get_handle<H>(&self) -> Option<&H> where
    H: 'static, 

Retrieve a handle and downcast it to return type and return a copy, otherwise None is returned

pub fn expect_handle<H>(&self) -> H where
    H: Clone + 'static, 

Get a handle from the given type (TypeId) and downcast it to a type H. If the item does not exist or the downcast fails, a panic occurs

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<Output = ()> + Send + 'static, 

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

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

Trait Implementations

impl Clone for ServiceInitializerContext

fn clone(&self) -> ServiceInitializerContext

Returns a copy of the value.

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

Performs copy-assignment from source.
