Struct DeltaPlannerTelemetry 

pub struct DeltaPlannerTelemetry {
    pub cache_reused: bool,
    pub fallback_decision: String,
    pub affected_sccs: usize,
    pub recomputed_sccs: usize,
    pub incremental_sccs: usize,

    pub measured_delta_speedup: Option<f64>,
    pub planner_advice: Vec<String>,
}

Planner-grade telemetry for a persistent-session relation delta update.

Fields

cache_reused: bool

True when the relation-delta path reused an existing session/cache.

fallback_decision: String

Planner decision used for this delta update.

affected_sccs: usize

Number of SCCs affected by the delta dependency closure.

recomputed_sccs: usize

Number of SCCs recomputed from scratch.

incremental_sccs: usize

Number of SCCs updated incrementally.

estimated_delta_speedup: Option<f64>

Estimated speedup of delta evaluation over full recompute when available.

measured_delta_speedup: Option<f64>

Measured speedup of delta evaluation over full recompute when both timings are available.

planner_advice: Vec<String>

Human-readable planner guidance for downstream diagnostics.

Implementations

impl DeltaPlannerTelemetry

pub fn from_delta_report( report: &LogicDeltaReport, cache_reused: bool, measured_micros: Option<(u64, u64)>, ) -> Self

Build planner telemetry from a delta report and optional timing evidence.

Trait Implementations

impl Clone for DeltaPlannerTelemetry

fn clone(&self) -> DeltaPlannerTelemetry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeltaPlannerTelemetry

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

Formats the value using the given formatter.

impl Default for DeltaPlannerTelemetry

fn default() -> DeltaPlannerTelemetry

Returns the “default value” for a type.

impl PartialEq for DeltaPlannerTelemetry

fn eq(&self, other: &DeltaPlannerTelemetry) -> 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.
