§TraceLog
Provides debug tracing macro for fine-grained execution step tracking.
§RESPONSIBILITIES
§Macro Definition
- Define TraceStep macro for trace-level logging
- Provide low-intrusion debug checkpoint logging
- Support formatted trace messages for step-by-step execution
§ARCHITECTURAL ROLE
§Position in Mountain
- Debug infrastructure module in Binary subsystem
- Cross-cutting concern available throughout the application
§Dependencies
- log: Logging framework
- trace: Trace level log filter
§Dependents
- All Binary subsystem modules for execution tracking
- Fn() main entry point for startup sequence logging
§SECURITY
§Considerations
- Macro expands to trace-level logs, does not modify runtime behavior
- No security impact, purely diagnostic
§PERFORMANCE
§Considerations
- Logs at TRACE level, filtered out in production builds
- Zero runtime cost when RUST_LOG does not include TRACE level
- Minimal code generation overhead from macro expansion
