One step in an execution trajectory (tool / adapter granularity).

Fields

step_id: String

timestamp_ms: i64

Unix epoch milliseconds.

adapter: String

operation: String

inputs_preview: Option<String>

outputs_preview: Option<String>

duration_ms: u64

success: bool

error: Option<String>

vitals: Option<CognitiveVitals>

freshness_at_step: Option<ContextFreshness>

frame_vars: Option<Value>

Optional per-step state snapshot (host-defined JSON, e.g. turn counters, budget).

tool_telemetry: Option<Value>

Optional structured tool telemetry (latency breakdown, I/O, HTTP, etc.).

Trait Implementations

impl Clone for TrajectoryStep

fn clone(&self) -> TrajectoryStep

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TrajectoryStep

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TrajectoryStep

fn deserialize<__D>( __deserializer: __D, ) -> Result<TrajectoryStep, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TrajectoryStep

fn eq(&self, other: &TrajectoryStep) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TrajectoryStep

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
