Runtime-file-state-to-json

Convert RuntimeFileState into a JsonValue. This helper exports both file sink status and queue metrics for combined runtime file diagnostics.

Interface

pub fn runtime_file_state_to_json(state : RuntimeFileState) -> @json_parser.JsonValue {}

input

• state : RuntimeFileState - Combined file and queue runtime snapshot.

output

• JsonValue - Structured JSON representation of the runtime file state.

Explanation

Detailed rules explaining key parameters and behaviors

• The output includes file, queued, pending_count, and dropped_count.
• file is itself exported as a nested file sink state object.
• This helper is richer than file_sink_state_to_json(...) because it also carries queue wrapping context.
• It is useful for RuntimeSink::file_runtime_state(), ConfiguredLogger::file_runtime_state(), and similar queued-file diagnostics flows.
• Any file_rotation_i64(...) policy nested under file includes both the compatibility max_bytes number and max_bytes_i64 as a string.

How to Use

Here are some specific examples provided.

When Need Structured Queued-file Diagnostics

When file and queue status should be exported together:

let value = runtime_file_state_to_json(snapshot)

In this example, callers receive a machine-readable combined runtime snapshot.

When Need Support Payload Composition

When queued file runtime data should be embedded into a larger JSON object:

match runtime.file_runtime_state() {
  Some(snapshot) => {
    let payload = runtime_file_state_to_json(snapshot)
    ignore(payload)
  }
  None => ()
}

In this example, the helper keeps file-plus-queue diagnostics in one reusable JSON value after the optional runtime snapshot is read.

Error Case

e.g.:

• If queued=false, the state still serializes normally with queue counters present.

• If callers need direct text output, stringify_runtime_file_state(...) is the better API.

Notes

1. Use this helper when file and queue runtime context should stay together.

2. It is especially useful for queued file runtime paths, whether accessed directly or through configured loggers.

3. For wide native rotation policies nested under file.rotation, use max_bytes_i64 when exact threshold recovery matters.
