Module ApplicationRunTime 

Application runtime module containing the struct definition. The struct is accessible as RunTime::ApplicationRunTime::ApplicationRunTime.

ApplicationRunTime (RunTime)

RESPONSIBILITIES

Main runtime struct that provides effect execution and lifecycle management capabilities for the Mountain application. Acts as the central coordinator between the Echo scheduler and application services.

ARCHITECTURAL ROLE

Core execution engine in Mountain’s architecture that bridges declarative effect system with high-performance task execution through Echo scheduler.

KEY COMPONENTS

• ApplicationRunTime: Main runtime struct holding Scheduler and Environment

ERROR HANDLING

All errors are propagated through Result types with detailed context. Shutdown operations use error recovery to continue cleanup even when individual services fail.

LOGGING

Uses log crate with appropriate severity levels:

• info: Initialization, successful completion
• debug: Detailed operation steps
• warn: Recoverable errors during shutdown
• error: Failed operations

PERFORMANCE CONSIDERATIONS

• Uses Arc for shared state to minimize cloning
• Scheduler handles parallel execution efficiently
• Shutdown operations are optimized to complete quickly

TODO

Medium Priority:

• Add effect execution metrics
• Implement effect cancellation support
• Add effect execution tracing

Low Priority:

• Add effect prioritization levels beyond Normal
• Implement circuit breaker pattern for failing effects
