Struct AsterRuntimeBuilder 

pub struct AsterRuntimeBuilder<S = ()> { /* private fields */ }

Builder for AsterRuntime.

Implementations

impl<S> AsterRuntimeBuilder<S>

pub fn shutdown_token(&self) -> &CancellationToken

Returns the runtime-owned shutdown token.

This accessor is primarily for shared component crates that implement AsterRuntimeComponent and need to spawn work using the same token the runtime cancels on termination signals, service completion, startup abort, or cancellation of a polled run.

pub fn component<C>(self, component: C) -> C::Output

where C: AsterRuntimeComponent<S>,

Adds one runtime component.

pub fn before_shutdown<F, Fut>(self, before_shutdown: F) -> Self

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

Registers a product hook that runs after the service future stops and before components.

pub fn build(self) -> Result<AsterRuntime<S>, AsterRuntimeError>

Builds the runtime runner.

Errors

Returns an error when component assembly previously failed, no service was registered, or the component dependency graph is invalid.

impl<S> AsterRuntimeBuilder<S>

where S: Future,

pub async fn run(self) -> Result<S::Output, AsterRuntimeError>

Builds and runs the runtime.

Errors

Returns assembly or startup/shutdown lifecycle errors.
