Struct QueryObservation 

pub struct QueryObservation {
    pub family: IndexFamily,
    pub hit: bool,
    pub latency_us: f64,
    pub recall: Option<f32>,
    pub predicted_cost: f64,
}

Single query observation reported back by the dispatcher after execution.

Fields

family: IndexFamily

Family that served the query.

hit: bool

Whether the query produced any results (used for hit/miss counting).

latency_us: f64

Observed wall-clock latency in microseconds.

recall: Option<f32>

Observed recall in [0.0, 1.0], or None when ground truth is unknown.

predicted_cost: f64

The cost the model predicted for this family at dispatch time.

Implementations

impl QueryObservation

pub fn new( family: IndexFamily, hit: bool, latency_us: f64, recall: Option<f32>, predicted_cost: f64, ) -> Self

Convenience constructor.

Trait Implementations

impl Clone for QueryObservation

fn clone(&self) -> QueryObservation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryObservation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QueryObservation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for QueryObservation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
