Struct ChoiceAnswer 

pub struct ChoiceAnswer {
    pub choice: String,
    pub probabilities: BTreeMap<String, f64>,
    pub confidence: f64,
}

The answer to a Choice.

• choice: the most probable option
• probabilities: every option mapped to its probability; they sum to 1
• confidence: how concentrated the distribution is, from 0 to 1. It is not the probability that the choice is right.

Fields

choice: String

probabilities: BTreeMap<String, f64>

confidence: f64

Implementations

impl ChoiceAnswer

pub fn is(&self, option: &str) -> bool

Whether option is the chosen one.

pub fn probability(&self, option: &str) -> f64

The probability of option, or 0 if the answer doesn’t list it.

pub fn ranked(&self) -> Vec<(&str, f64)>

The options with their probabilities, most probable first. Useful for a “did you mean” prompt.
