Struct Distribution 

pub struct Distribution { /* private fields */ }

Non-negative mass over declared options, summing to 1 within tolerance. Uncalibrated: it is not a calibrated probability.

Implementations

impl Distribution

pub fn new( options: &[String], map: &BTreeMap<String, f64>, tolerance: Decimal, ) -> Result<Self, KindError>

Validate a supplied distribution. Stored as supplied, never renormalized.

pub fn from_logits( options: &[String], map: &BTreeMap<String, f64>, tolerance: Decimal, ) -> Result<Self, KindError>

Normalize logits by softmax (design 8.2: the core normalizes logits, it never invents mass for a label backend).

pub fn options(&self) -> &[String]

pub fn masses(&self) -> &[f64]

pub fn mass(&self, option: &str) -> Option<f64>

pub fn top(&self) -> (&str, f64)

The top option; ties go to the earlier declared option.
