Read the effective file path used by a file-backed `RuntimeSink`. This helper is useful for diagnostics, support output, and confirming which direct runtime file sink is active.
`file_path()` is the compatibility form. For truthful file-semantics detection, prefer `file_path_or_none()`.
### Interface
```moonbit
@@ -36,6 +38,8 @@ Detailed rules explaining key parameters and behaviors
- Plain `File` runtime variants return their current file path.
- `QueuedFile` runtime variants forward the wrapped inner file sink path.
- Non-file runtime variants return an empty string.
- This fallback keeps older callers source-compatible, but it does not distinguish “not file-backed” from “file-backed with an empty-looking value”.
- New diagnostic code should prefer `file_path_or_none()` when it must avoid fallback values.
- This helper is observation-only and does not modify file state.
### How to Use
@@ -65,10 +69,12 @@ In this example, the path can be surfaced without reading broader runtime state.
e.g.:
- If the runtime sink is not file-backed, the method returns an empty string.
- If callers need richer file status than just the path, `file_state()` or `file_runtime_state()` is the better API.
- If callers need a truthful file-semantics check, use `file_path_or_none()`.
- If callers need richer file status than just the path, `file_state_or_none()` or `file_runtime_state()` is the better API.
### Notes
1. Use this helper for direct runtime path visibility on `RuntimeSink` values.
2. Empty string usually means the runtime sink is not file-backed.
2. Empty string is a compatibility fallback; `file_path_or_none()` is the recommended truthful API.
