Crate fuel_core_services

Common traits and logic for managing the lifecycle of services

Modules

• stream
  Re-exports for streaming utilities
• yield_stream
  Stream that yields each batch_size items allowing other tasks to work.

Structs

• AsyncProcessor
  A processor that can execute async tasks with a limit on the number of tasks that can be executed concurrently.
• EmptyShared
  Used if services have no asynchronously shared data
• ServiceRunner
  The service runner manages the lifecycle, execution and error handling of a RunnableService. It can be cloned and passed between threads.
• SharedMutex
  A mutex that can safely be in async contexts and avoids deadlocks.
• StateWatcher
  The wrapper around the watch::Receiver<State>. It repeats the Receiver functionality + a new one.

Enums

• State
  The lifecycle state of the service

Traits

• RunnableService
  Trait used by ServiceRunner to encapsulate the business logic tasks for a service.
• RunnableTask
  The trait is implemented by the service task and contains a single iteration of the infinity loop.
• Service
  Trait for service runners, providing a minimal interface for managing the lifecycle of services such as start/stop and health status.
• TraceErr
  Helper trait to trace errors
