Tracing

Resources:

Rule of thumb for log level

• ERROR: Operation fails, and the failure is user- or system-visible
• WARN: Something's off but handled
• INFO: "What happened" narrative of a request/task lifecycle
• DEBUG: Anything you'd want when tracking down a bug but that would clutter normal logs
• TRACE: Very verbose internals (line by line flow), usually per-crate/module scoped when you turn it on
