trait HasDegradationState[E <: CantonError] extends AnyRef
This trait should be implemented by classes that can experience a degradation. It has methods that enable the tracking and logging-upon-resolution of stateful degradation. Example scenario:
- A participant is anomalously disconnect from domain -> we log an error and track that the error/degradation has occurred
- The participant is reconnected to the domain -> we log a resolution message referring to the previous error and log that the degradation has been fixed For an example use of this trait see CantonSyncService
- E
