Struct Choice 

pub struct Choice { /* private fields */ }

A choice among ordered named outcomes.

Implementations

impl Choice

pub fn new( text: impl Into<String>, options: IndexMap<String, Option<String>>, ) -> Result<Self, Error>

Validate instructions and at least two distinct nonempty option names.

Errors

Returns InvalidQuestion for blank instructions, fewer than two options, or an empty option name. The ordered map supplies unique names.

pub fn options(&self) -> &IndexMap<String, Option<String>>

Ordered option names and descriptions.

impl Choice

pub fn instructions(&self) -> &str

Original instructions, preserved without trimming.

pub fn min_confidence(&self) -> f64

Minimum confidence required for a decision.

pub fn with_min_confidence(self, value: f64) -> Result<Self, Error>

Set a finite confidence threshold in [0, 1].

Errors

Returns InvalidQuestion if the threshold is nonfinite or outside [0, 1].
