Stringify-queue-config

Serialize QueueConfig into JSON text. This helper is the most direct export path for synchronous queue wrapper configuration when callers want immediate string output.

Interface

pub fn stringify_queue_config(queue : QueueConfig, pretty~ : Bool = false) -> String {}

input

• queue : QueueConfig - Queue wrapper configuration to serialize.
• pretty : Bool - Whether JSON should be pretty-printed.

output

• String - Serialized JSON text for the queue config.

Explanation

Detailed rules explaining key parameters and behaviors

• pretty=false returns compact JSON suitable for logs and snapshots.
• pretty=true returns indented JSON for human inspection.
• This helper is built on top of queue_config_to_json(...).
• Internally it serializes the Json result with value.stringify(...) or value.stringify(indent=2), so the text form stays aligned with the structured export helper.
• The resulting text follows the same queue schema accepted by config parsing flows.

How to Use

Here are some specific examples provided.

When Need Config Text For Humans

When queue settings should be printed or pasted into docs:

println(stringify_queue_config(QueueConfig::new(32), pretty=true))

In this example, the output is formatted for readability.

When Need Compact Generated Output

When queue config should stay small:

let text = stringify_queue_config(
  QueueConfig::new(8, overflow=QueueOverflowPolicy::DropNewest),
)

In this example, compact JSON is returned without extra formatting.

Error Case

e.g.:

• If callers need a Json for further composition, this API is the wrong layer and queue_config_to_json(...) should be used instead.

• If queue policy is too aggressive for workload burst size, serialization still succeeds because this helper only exports config.

Notes

1. Use this helper when the next consumer expects JSON text instead of Json.

2. Use queue_config_to_json(...) when you still need to embed the queue config inside a larger JSON object before final stringification.
