## Stringify-file-sink-policy
|
|
|
|
Serialize `FileSinkPolicy` into JSON text. On the root `src` facade, this helper forwards to the concrete stringifier owned by `src/file_model`.
|
|
|
|
### Interface
|
|
|
|
```moonbit
|
|
pub fn stringify_file_sink_policy(policy : FileSinkPolicy, pretty~ : Bool = false) -> String {}
|
|
```
|
|
|
|
#### input
|
|
|
|
- `policy : FileSinkPolicy` - File sink runtime policy to serialize.
|
|
- `pretty : Bool` - Whether JSON should be pretty-printed.
|
|
|
|
#### output
|
|
|
|
- `String` - Serialized JSON text for the file policy.
|
|
|
|
### Explanation
|
|
|
|
Detailed rules explaining key parameters and behaviors
|
|
|
|
- `pretty=false` returns compact JSON.
|
|
- `pretty=true` returns indented JSON for human inspection.
|
|
- The root surface forwards to `@file_model.stringify_file_sink_policy(...)`, which is the real owner of this formatting logic.
|
|
- This helper builds on top of `file_sink_policy_to_json(...)`.
|
|
- The output is suited for support dumps, policy snapshots, and generated diagnostics text.
|
|
- Typical inputs come from `FileSink::policy()`, `RuntimeSink::file_policy()`, or `ConfiguredLogger::file_policy()`.
|
|
|
|
### How to Use
|
|
|
|
Here are some specific examples provided.
|
|
|
|
#### When Need Human-readable Policy Output
|
|
|
|
When current file policy should be printed for diagnostics:
|
|
```moonbit
|
|
println(stringify_file_sink_policy(runtime.file_policy(), pretty=true))
|
|
```
|
|
|
|
In this example, the runtime file policy is rendered in readable JSON.
|
|
|
|
#### When Need Compact Policy Export
|
|
|
|
When a file policy snapshot should stay small:
|
|
```moonbit
|
|
let text = stringify_file_sink_policy(runtime.file_policy())
|
|
```
|
|
|
|
In this example, compact JSON is produced without extra formatting logic.
|
|
|
|
### Error Case
|
|
|
|
e.g.:
|
|
- If callers need a `Json` for composition rather than text, `file_sink_policy_to_json(...)` is the better API.
|
|
|
|
- If rotation is disabled, the output still includes `rotation` as `null`.
|
|
|
|
### Notes
|
|
|
|
1. Use this helper for direct textual policy snapshots.
|
|
|
|
2. `pretty=true` is useful when operators or support tooling are the audience.
