Struct InferObservation 

pub struct InferObservation { /* private fields */ }

Available on crate feature decode only.

Bounded per-key observations over one window, fed one sample at a time.

Keys are projected through describe_key under base; a key that does not parse, or sits on a verbatim plane, is counted and skipped — there is no [[subject]] to draft for it.

Implementations

impl InferObservation

pub fn new(base: &str, max_keys: usize, max_paths: usize) -> InferObservation

pub fn observe( &mut self, key: &str, at_s: f64, encoding: Option<&str>, qos: Option<&str>, doc: Option<&Value>, )

Feed one sample. qos is the label the caller resolved for the wire’s axes (a profile name when one matches, else the axes spelled out); doc the structural document when the payload carried one (crate::model::decode::structural_value) — None counts it as undocumented rather than pretending its fields were absent.

pub fn observe_unread( &mut self, key: &str, at_s: f64, encoding: Option<&str>, qos: Option<&str>, )

A sample whose payload was too large to read (O6): counted, never read as an absent document.

pub fn samples(&self) -> u64

pub fn keys_seen(&self) -> usize

pub fn keys_refused(&self) -> u64

pub fn span_s(&self) -> f64

First to last sample, seconds (0 for fewer than two samples).
