- This helper delegates to `log(Level::Trace, ..., fields=fields)`.
|
||||
- The record is still subject to min-level gating, patching, filtering, and overflow policy.
|
||||
- This helper does not accept a per-call target override. It uses the logger's stored target unless the logger was derived earlier with `with_target(...)` or `child(...)`.
|
||||
- Trace records are often skipped in production because they are the lowest built-in severity.
|
||||
- Use this helper when explicit trace intent is clearer than a raw `log(...)` call.
