Struct LifecycleManager 

pub struct LifecycleManager<R: ContainerRuntime + 'static> { /* private fields */ }

Coordinates the startup, supervision and shutdown of every resource declared in a LifecyclePlan.

Implementations

impl<R: ContainerRuntime + 'static> LifecycleManager<R>

pub fn new( plan: LifecyclePlan, runtime: R, ) -> (Self, UnboundedReceiver<LifecycleEvent>)

Build a manager bound to plan and runtime. Returns the event stream receiver alongside.

pub async fn start_all(&self) -> Result<(), LifecycleError>

Start every resource in topological order. Independent branches start in parallel. On the first failure, the resources that already started are stopped automatically before the error is returned.

pub async fn stop_all(&self, grace: Duration) -> Result<(), LifecycleError>

Stop every resource in reverse topological order with the given SIGTERM-to-SIGKILL grace window.

pub async fn run_until_signal( &self, grace: Duration, ) -> Result<(), LifecycleError>

Opinionated entry point used by lightshuttle up: starts the stack, waits for SIGINT or SIGTERM, then stops the stack cleanly with the configured grace window.
