Struct LlmCallParams 

pub struct LlmCallParams<'a> {
    pub name: &'a str,
    pub request: &'a LlmRequest,
    pub parent: Option<&'a ScopeHandle>,
    pub attributes: LlmAttributes,
    pub data: Option<Json>,
    pub metadata: Option<Json>,
    pub model_name: Option<String>,
    pub annotated_request: Option<Arc<AnnotatedLlmRequest>>,
    pub timestamp: Option<DateTime<Utc>>,
}

Builder parameters for llm_call.

Fields

name: &'a str

Logical provider or model family name recorded on the span.

request: &'a LlmRequest

Raw request associated with the span.

parent: Option<&'a ScopeHandle>

Optional explicit parent scope.

attributes: LlmAttributes

LLM attribute bitflags applied to the 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 the start event.

model_name: Option<String>

Optional normalized model name recorded separately from the request payload.

annotated_request: Option<Arc<AnnotatedLlmRequest>>

Optional normalized request annotation produced by a codec.

timestamp: Option<DateTime<Utc>>

Optional timestamp captured as the handle start time and reused by the emitted start event. When omitted, the current UTC time is used.

Implementations

impl<'a> LlmCallParams<'a>

pub fn builder() -> LlmCallParamsBuilder<'a, ((), (), (), (), (), (), (), (), ())>

Create a builder for building LlmCallParams. On the builder, call .name(...), .request(...), .parent(...)(optional), .attributes(...)(optional), .data(...)(optional), .metadata(...)(optional), .model_name(...)(optional), .annotated_request(...)(optional), .timestamp(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of LlmCallParams.
