Struct Report 

pub struct Report {
    pub per_example: Vec<ExampleReport>,
    pub summary: HashMap<String, ScoreSummary>,
    pub failures: Vec<FailureRecord>,
    pub cost: OverallCost,
    pub run_id: String,
}

Evaluation report (with original text, stddev, failure list; deserializable).

Fields

per_example: Vec<ExampleReport>

Per-example complete records (including input/reference/prediction originals)

summary: HashMap<String, ScoreSummary>

Per-evaluator summaries (mean + stddev + sample count)

failures: Vec<FailureRecord>

Failure records collected by per-item tolerance (empty = all succeeded)

cost: OverallCost

Cost ledger for the run (E1). Old reports without this field deserialize to the default.

run_id: String

Stable identifier of this evaluation run (B9): the join key against traces/spans.

Set explicitly via EvalRunner::with_run_id or auto-generated as a UUID v4 when the runner runs. The predictor receives it through Predictor::begin_run so a system under test can stamp it (e.g. into RunnableConfig.metadata["trace_id"], which the agent executor propagates to callback/OTel spans). Old reports deserialize to an empty id.

Implementations

impl Report

pub fn to_jsonl(&self) -> String

Renders the report as JSONL: one example record per line, carrying the run id.

{"run_id":"...","index":0,"input":"...","reference":"...","prediction":"...",
 "contexts":["..."],"scores":{"exact_match":{"value":1.0}}}

pub async fn write_jsonl(&self, path: impl AsRef<Path>) -> Result<(), EvalError>

Writes Self::to_jsonl to path (async, truncating/overwriting).

pub fn to_table(&self) -> String

Renders a fixed-width, dependency-free plain-text view of the report.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for Report

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Report

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Report

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

where __S: Serializer,
