> Run the registered LLM conditional execution guardrail chain.

Generated from `cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-pii-redaction -p nemo-relay-ffi -p nemo-relay-types -p nemo-relay-plugin -p nemo-relay-worker-proto -p nemo-relay-worker`.

<pre />

Run the registered LLM conditional execution guardrail chain.

Returns `NemoRelayStatus::Ok` if all guardrails pass, or `NemoRelayStatus::GuardrailRejected` if blocked.

## Parameters

* `native_json`: The request payload as a JSON C string representing an `LlmRequest` (`{"headers": {...}, "content": {...}}`).

## Returns

Returns [`NemoRelayStatus::Ok`](/reference/api/rust-library-reference/nemo-relay-ffi/error/enum-nemorelaystatus) when execution is allowed and [`NemoRelayStatus::GuardrailRejected`](/reference/api/rust-library-reference/nemo-relay-ffi/error/enum-nemorelaystatus) when a guardrail blocks the call.

## Safety

All pointers must be valid.
