Struct Trajectory 

pub struct Trajectory {
    pub steps: Vec<Step>,
    pub model_calls: usize,
    pub tool_calls: usize,
    pub input_tokens: u32,
    pub output_tokens: u32,
    pub ended: bool,
}

A run flattened into ordered Steps plus totals.

Fields

steps: Vec<Step>

model_calls: usize

tool_calls: usize

input_tokens: u32

output_tokens: u32

ended: bool

An End event was seen. A log without one was cut off.

Implementations

impl Trajectory

pub fn from_events(events: &[SessionEvent]) -> Self

Build the normalized view from recorded events.

A PreTool starts a tool step already marked failed (“no result”); the matching PostTool (same call_id) overwrites that. Doing it in this order means a run that died mid-call is visible as a failure instead of the call silently vanishing.

pub fn load(path: &Path) -> Result<Self>

Read a JSONL session log and normalize it.

pub fn tool_sequence(&self) -> Vec<String>

Tool names in call order: the structure of the run.

pub fn compare_to_golden(&self, golden: &Trajectory) -> GoldenDiff

Compare this run’s tool sequence with a known good one.

Trait Implementations

impl Clone for Trajectory

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Trajectory

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

Formats the value using the given formatter.

impl Default for Trajectory

fn default() -> Self

Returns the “default value” for a type.
