> Builder parameters for `llm_stream_call_execute`.

Generated from `cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-ffi`.

<pre />

Builder parameters for [`llm_stream_call_execute`](/reference/api/rust-library-reference/nemo-relay/api/llm/fn-llm-stream-call-execute).

## Fields

### `name: String`

Logical provider or model family name recorded on emitted events.

### `request: LlmRequest`

Raw request passed into the managed pipeline.

### `func: LlmStreamExecutionNextFn`

Streaming provider callback or execution continuation.

### `collector: LlmCollectorFn`

Per-chunk collector callback used to accumulate stream state.

### `finalizer: LlmFinalizerFn`

Finalizer callback used to construct the completed response.

### `parent: Option<ScopeHandle>`

Optional explicit parent scope for the emitted LLM span.

### `attributes: LlmAttributes`

LLM attribute bitflags applied to the managed span.

### `data: Option<Json>`

Optional application payload stored on the handle but not emitted as Agent Trajectory Observability Format (ATOF) data.

### `metadata: Option<Json>`

Optional JSON metadata recorded on emitted events.

### `model_name: Option<String>`

Optional normalized model name for observability output.

### `codec: Option<Arc<dyn LlmCodec>>`

Optional request codec used to produce annotated request data.

### `response_codec: Option<Arc<dyn LlmResponseCodec>>`

Optional response codec used to attach annotated response data.

## Implementations

### `impl LlmStreamCallExecuteParams`

<pre />

#### `builder`

<pre />

Create a builder for building `LlmStreamCallExecuteParams`. On the builder, call `.name(...)`, `.request(...)`, `.func(...)`, `.collector(...)`, `.finalizer(...)`, `.parent(...)`(optional), `.attributes(...)`(optional), `.data(...)`(optional), `.metadata(...)`(optional), `.model_name(...)`(optional), `.codec(...)`(optional), `.response_codec(...)`(optional) to set the values of the fields. Finally, call `.build()` to create the instance of `LlmStreamCallExecuteParams`.
