#[non_exhaustive]
pub enum ChartRule {

A control chart pattern rule.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

WE1

WE1: Any single point beyond 3σ.

WE2

WE2: 2 of 3 consecutive points beyond 2σ on the same side.

Multiple overlapping windows may detect the same event; deduplicate by index if needed.

WE3

WE3: 4 of 5 consecutive points beyond 1σ on the same side.

Multiple overlapping windows may detect the same event; deduplicate by index if needed.

WE4

WE4: 8 consecutive points on the same side of center.

Nelson5

Nelson5: 6 points in a row steadily increasing or decreasing.

Nelson6

Nelson6: 14 points in a row alternating up and down.

Nelson7

Nelson7: 15 consecutive points within 1σ of center (stratification).

CustomRun

Custom run rule: n_points consecutive points beyond k_sigma.

Fields

n_points: usize

Number of consecutive points required.

k_sigma: f64

Sigma threshold.

Trait Implementations

impl Clone for ChartRule

fn clone(&self) -> ChartRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChartRule

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

Formats the value using the given formatter.

impl PartialEq for ChartRule

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