Struct ResidualSample 

pub struct ResidualSample {
    pub t: f64,
    pub class: ResidualClass,
    pub value: f64,
    pub channel: Option<String>,
}

A single residual sample. t is logical time (seconds since stream start). value is the residual quantity in the class-specific natural units (the units are documented per class in the paper’s Table 2).

Fields

t: f64

class: ResidualClass

value: f64

The residual itself: actual − expected (or actual / expected for cardinality, log-transformed). Never NaN; missing values are dropped at the adapter boundary so downstream code can rely on this.

channel: Option<String>

Optional channel discriminator (e.g. plan_hash, table id, wait_event name). Used by the motif grammar to scope episodes.

Implementations

impl ResidualSample

pub fn new(t: f64, class: ResidualClass, value: f64) -> Self

pub fn with_channel(self, channel: impl Into<String>) -> Self
