## Runtime-sink-file-reset-policy
|
|
|
|
Reset the runtime file policy of a `RuntimeSink` back to its captured defaults.
|
|
|
|
### Interface
|
|
|
|
```moonbit
|
|
pub fn RuntimeSink::file_reset_policy(self : RuntimeSink) -> Bool {
|
|
```
|
|
|
|
### Explanation
|
|
|
|
Detailed rules explaining key parameters and behaviors
|
|
|
|
- Plain `File` runtime variants restore the wrapped `FileSink` default policy and return `true`.
|
|
- `QueuedFile` runtime variants restore the wrapped inner `FileSink` default policy only when no queued records are pending.
|
|
- Non-file runtime variants return `false`.
|
|
- If a queued file sink still has pending records, the reset is rejected and returns `false` so already queued records are not later written under a different policy than the one they were queued under.
|
|
|
|
### Notes
|
|
|
|
1. Use this helper when runtime file policy should return to its captured defaults.
|
|
|
|
2. On queued file sinks, clear pending records first so policy mutation does not retroactively affect already queued writes.
