Trait HealthObserve

    // Required method

        &'life0 self,
        target: &'life1 Backend,

HealthObserve is an interface for observing health changes of backends, this is what’s used for our health observation callback.

Required Methods

fn observe<'life0, 'life1, 'async_trait>( &'life0 self, target: &'life1 Backend, healthy: bool, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Observes the health of a Backend, can be used for monitoring purposes.
