Struct ConfidenceSnapshot 

pub struct ConfidenceSnapshot {
    pub mean: f32,
    pub variance: f32,
    pub sample_count: u32,
    pub is_stable: bool,
}

A snapshot of the current Bayesian posterior for an asset’s confidence.

Fields

mean: f32

Posterior mean: α / (α + β).

variance: f32

Posterior variance: αβ / ((α+β)²(α+β+1)).

sample_count: u32

Total observations (successes + failures) since the updater was created.

is_stable: bool

true when sample_count ≥ 10 and variance < 0.01, indicating a stable credible interval.

Trait Implementations

impl Clone for ConfidenceSnapshot

fn clone(&self) -> ConfidenceSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfidenceSnapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ConfidenceSnapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ConfidenceSnapshot

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
