Struct ObservationBody 

pub struct ObservationBody {

    pub id: String,
    pub trace_id: String,
    pub parent_observation_id: Option<String>,
    pub name: Option<String>,
    pub start_time: Option<String>,
    pub end_time: Option<String>,
    pub input: Option<Value>,
    pub output: Option<Value>,
    pub metadata: Option<Value>,
    pub level: Option<ObservationLevel>,
    pub status_message: Option<String>,
    pub environment: Option<String>,
    pub model: Option<String>,
    pub usage_details: Option<Map<String, Value>>,
}

Body of an observation (generation / span).

Generation and span share the same set of body fields — they differ only in the event type and whether model / usageDetails are present (span usually does not carry them).

Fields

id: String

Observation id. Sending the same id twice results in a merge (first create, then update endTime).

trace_id: String

The trace ID this observation belongs to.

parent_observation_id: Option<String>

Parent observation; None means it is directly attached to the trace.

name: Option<String>

start_time: Option<String>

end_time: Option<String>

input: Option<Value>

output: Option<Value>

metadata: Option<Value>

level: Option<ObservationLevel>

status_message: Option<String>

environment: Option<String>

model: Option<String>

The model name (generation only).

usage_details: Option<Map<String, Value>>

Free-form token usage details: keys are arbitrary; if total is omitted, the backend infers it. We populate input / output / cache_read_input_tokens / cache_creation_input_tokens (aligned with defect_agent::llm::Usage).

Trait Implementations
