Module observability_traits 

Structs

LlmMessageSnapshot

Full prompt/completion content for one llm.call, captured and credential-scrubbed at the agent-loop boundary so the OTel exporter can emit gen_ai.input.messages / gen_ai.output.messages / gen_ai.system_instructions.

MessageSnapshot

A single conversation message captured for OTel GenAI semconv export. Structurally mirrors crate::model_provider::ChatMessage but is defined independently to keep the observability API decoupled from the model-provider API and to signal that content has been credential-scrubbed at capture time.

ToolCallSnapshot

A tool call the model emitted, captured for gen_ai.output.messages. arguments_json is the raw JSON arguments string, credential-scrubbed.

TurnTokenUsage

Token usage breakdown for a single agent turn.

Enums

ObserverEvent

Discrete events emitted by the agent runtime for observability.

ObserverMetric

Numeric metrics emitted by the agent runtime.

Traits
