Required Methods§

Source

fn register<'life0, 'async_trait>( &'life0 self, instance: ServiceInstance, ) -> Pin<Box<dyn Future<Output = Result<(), DiscoveryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Register a service instance. Returns error if registration fails.

Source

fn discover<'life0, 'life1, 'async_trait>( &'life0 self, service_name: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<ServiceInstance>, DiscoveryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Discover all healthy instances of a service.

Source

fn heartbeat<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, service_name: &'life1 str, instance_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), DiscoveryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Send a heartbeat to keep registration alive.

Source

fn deregister<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, service_name: &'life1 str, instance_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), DiscoveryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Remove a service instance from the registry.

Source

fn watch<'life0, 'life1, 'async_trait>( &'life0 self, service_name: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<WatchStream, DiscoveryError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Watch for changes to a service’s instances. Returns a stream of instance lists.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
