Struct Registry 

pub struct Registry { /* private fields */ }

Ordered component registry.

Components start in registration order and stop in reverse registration order, ensuring dependants shut down before their dependencies.

Implementations

impl Registry

pub fn new() -> Self

Create an empty Registry with default settings.

pub fn with_config(config: RegistryConfig) -> Self

Create a registry with custom RegistryConfig.

pub fn register(&mut self, component: Arc<dyn Component>)

Register a component. Registration order determines startup order.

pub async fn start_all(&self) -> AppResult<()>

Start all startable components in registration order.

pub async fn start_all_concurrent( &self, cancel: CancellationToken, ) -> AppResult<()>

Start all components concurrently, limited by RegistryConfig::concurrency.

pub async fn stop_all(&self) -> AppResult<()>

Stop all running components in reverse registration order.

pub async fn stop_all_detailed(&self) -> Vec<StopResult>

Stop all running components in reverse registration order with per-component results.

pub fn health_all(&self) -> Vec<Health>

Collect health for all registered components without holding the registry lock while component health is evaluated.

pub fn state(&self, name: &str) -> Option<State>

Return the tracked state for the named component.

pub fn len(&self) -> usize

Return the number of registered components.

pub fn is_empty(&self) -> bool

Return true if no components have been registered.

Trait Implementations

fn default() -> Self

Returns the “default value” for a type.
