Struct StepReport 

#[non_exhaustive]
pub struct StepReport {
    pub phase: StepPhase,
    pub progress: StepProgress,
    pub step_computed_vertices: usize,
    pub step_elapsed: Duration,
    pub changed: StepDelta,
    pub longest_unit: Option<SlowUnitReport>,
    pub result: Option<EvalResult>,
}

Per-step locations and telemetry. Reads between steps observe installed new values alongside old values for still-pending cells. Only Finished carries a result; Cancelled is terminal for explicit jobs.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

phase: StepPhase

Phase reached at return.

progress: StepProgress

Formula progress, with a pass-specific denominator.

step_computed_vertices: usize

Formulas computed during this step.

step_elapsed: Duration

Active elapsed time in this step.

changed: StepDelta

Regions changed by installed work in this step.

longest_unit: Option<SlowUnitReport>

Longest atomic unit, if any ran.

result: Option<EvalResult>

Present only when phase is Finished.
