Stringify-async-runtime-state

Serialize AsyncRuntimeState into JSON text. This helper is the most direct reporting path for async runtime mode and background worker capability.

Interface

pub fn stringify_async_runtime_state(
  state : AsyncRuntimeState,
  pretty~ : Bool = false,
) -> String {}

input

• state : AsyncRuntimeState - Runtime capability snapshot to serialize.
• pretty : Bool - Whether JSON should be pretty-printed.

output

• String - Serialized JSON text for the runtime state.

Explanation

Detailed rules explaining key parameters and behaviors

• pretty=false returns compact JSON.
• pretty=true returns indented JSON for human diagnostics.
• This helper is built on top of async_runtime_state_to_json(...).
• Internally it serializes the JsonValue result with @json_parser.stringify(...) or @json_parser.stringify_pretty(value, 2), so the text form stays aligned with the structured runtime-state export helper.
• The compact form matches the tested snapshot shape such as {"mode":"native_worker","background_worker":true}.
• It is well-suited for startup banners, support reports, and target capability logs.

How to Use

Here are some specific examples provided.

When Need Human-readable Runtime Diagnostics

When capability information should be printed during startup:

println(stringify_async_runtime_state(async_runtime_state(), pretty=true))

In this example, the runtime state is emitted in a readable form.

When Need Compact Capability Logs

When runtime info should stay small in structured logs:

let text = stringify_async_runtime_state(async_runtime_state())

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

Error Case

e.g.:

• If callers need a JSON value rather than text, they should use async_runtime_state_to_json(...) instead.

• If more complete async logger diagnostics are required, this helper should be replaced with stringify_async_logger_state(...).

Notes

1. The compact output uses the same canonical mode labels as async_runtime_mode_label(...).

2. This helper is the direct text form of the same two-field runtime snapshot exported by async_runtime_state_to_json(...).

3. Use async_runtime_state_to_json(...) when the next consumer still needs a JsonValue for composition before final stringification.
