Queue-config-to-json

Convert a typed QueueConfig into a JsonValue. This helper is the structured export path for synchronous queue wrapper configuration when callers want machine-readable config output.

Interface

pub fn queue_config_to_json(queue : QueueConfig) -> @json_parser.JsonValue {}

input

• queue : QueueConfig - Queue wrapper configuration created in code or parsed from config text.

output

• JsonValue - Structured JSON representation of the queue config.

Explanation

Detailed rules explaining key parameters and behaviors

• The output includes max_pending and overflow.
• Overflow is serialized using the supported config labels such as DropNewest and DropOldest.
• This helper is intended for config export rather than runtime queue inspection.
• The JSON shape matches the queue section accepted by parse_logger_config_text(...).

How to Use

Here are some specific examples provided.

When Need Structured Queue Config Export

When queue settings should be embedded into a larger JSON payload:

let queue_json = queue_config_to_json(
  QueueConfig::new(64, overflow=QueueOverflowPolicy::DropOldest),
)

In this example, callers receive a reusable JSON value instead of a final string.

When Need Roundtrip-friendly Config Data

When code generates queue policy and later persists it:

let value = queue_config_to_json(QueueConfig::new(16))

In this example, the exported shape stays aligned with the supported parser schema.

Error Case

e.g.:

• If max_pending is very small, the config still serializes successfully even though runtime drops may happen more often.

• If callers need direct text output instead of a JSON value, they should use stringify_queue_config(...) instead.
