ATIF trajectories and a runtime-bound trajectory collector.

## Structs

* [AtifAgentInfo](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atifagentinfo): Information about the agent that produced the trajectory.
* [AtifAncestry](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atifancestry): Lineage node identifying a callable within an ATIF step.
* [AtifExporter](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atifexporter): Collect lifecycle events using the SDK's scope and normalization services.
* [AtifFinalMetrics](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atiffinalmetrics): Aggregate statistics for the entire trajectory (ATIF final_metrics).
* [AtifInvocationInfo](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atifinvocationinfo): Invocation timing and correlation metadata for one execution occurrence.
* [AtifMetrics](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atifmetrics): Token usage and cost metrics for a single step.
* [AtifObservation](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atifobservation): Observation results from tool execution.
* [AtifObservationResult](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atifobservationresult): A single observation result from a tool call.
* [AtifStep](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atifstep): A single step in an ATIF trajectory.
* [AtifStepExtra](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atifstepextra): Lineage payload serialized into ATIF `Step.extra`.
* [AtifSubagentTrajectoryRef](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atifsubagenttrajectoryref): Reference to a delegated subagent trajectory.
* [AtifToolCall](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atiftoolcall): A tool call made by the agent.
* [AtifTrajectory](/reference/api/rust-library-reference/nemo-relay/exporter/atif/struct-atiftrajectory): A complete ATIF trajectory.

## Constants

* [ATIF_SCHEMA_VERSION](/reference/api/rust-library-reference/nemo-relay/exporter/atif/constant-atif-schema-version): The ATIF schema version string embedded in all exported trajectories.
