Struct TrajectoryNode 

pub struct TrajectoryNode {
    pub episode_id: Uuid,
    pub recorded_at: i64,
    pub session_id: String,
    pub project_id: Option<String>,
    pub ainl_source_hash: Option<String>,
    pub outcome: TrajectoryOutcome,
    pub steps: Vec<TrajectoryStep>,
    pub duration_ms: u64,
    pub frame_vars: Option<Value>,
    pub fitness_delta: Option<f32>,
}

Execution trajectory: tool/adapter steps for learning and replay (schema from ainl_contracts).

Fields

episode_id: Uuid

Episode this trajectory augments.

recorded_at: i64

Unix seconds when the trajectory was recorded.

session_id: String

project_id: Option<String>

ainl_source_hash: Option<String>

outcome: TrajectoryOutcome

steps: Vec<TrajectoryStep>

duration_ms: u64

frame_vars: Option<Value>

Optional end-of-episode frame snapshot (JSON) — e.g. vitals + compression summary.

fitness_delta: Option<f32>

Optional host-learner “fitness” or improvement signal (e.g. vitals trust, Δ reward).

Trait Implementations

impl Clone for TrajectoryNode

fn clone(&self) -> TrajectoryNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrajectoryNode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TrajectoryNode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TrajectoryNode

fn eq(&self, other: &TrajectoryNode) -> 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 TrajectoryNode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
