Enum ChangeClassification 

pub enum ChangeClassification {
    Noise,
    Suspected,
    Probable,
}

Coarse-grained change-feed classification.

The bands are the policy surface — the detector bins each target into exactly one band and emits an event when the per-target band is Suspected or Probable. The Noise band is the “no event” default.

Variants

Noise

Per-target score below the noise_ceiling. No event is emitted; the delta is logged.

Suspected

Per-target score between noise_ceiling and probable_floor. An advisory event is emitted so operators can annotate the target.

Probable

Per-target score at or above probable_floor. A runbook event is emitted and the runbook diagnostics surface is triggered.

Implementations

impl ChangeClassification

pub const fn label(self) -> &'static str

Stable lower-case wire label.

Example

use stygian_charon::change_feed::ChangeClassification;

assert_eq!(ChangeClassification::Noise.label(), "noise");
assert_eq!(ChangeClassification::Suspected.label(), "suspected");
assert_eq!(ChangeClassification::Probable.label(), "probable");

pub const fn emits_event(self) -> bool

true for the two bands that emit events.

Trait Implementations

impl Clone for ChangeClassification

fn clone(&self) -> ChangeClassification

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeClassification

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChangeClassification

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ChangeClassification

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ChangeClassification

fn cmp(&self, other: &ChangeClassification) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ChangeClassification

fn eq(&self, other: &ChangeClassification) -> 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 PartialOrd for ChangeClassification

fn partial_cmp(&self, other: &ChangeClassification) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ChangeClassification

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
