Struct Boolean 

pub struct Boolean { /* private fields */ }

A Boolean question with optional descriptions of each outcome.

Implementations

impl Boolean

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

Validate instructions and construct a question without a confidence threshold.

Errors

Returns InvalidQuestion when instructions are empty or contain only reference-defined whitespace.

pub fn with_descriptions(self, yes: Option<String>, no: Option<String>) -> Self

Set descriptions for true and false, respectively.

pub fn true_description(&self) -> Option<&str>

Description of the true outcome.

pub fn false_description(&self) -> Option<&str>

Description of the false outcome.

impl Boolean

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].
