Struct Decision 

pub struct Decision {
    pub question: Question,
    pub options_from: Option<String>,
    pub none: Option<String>,
    pub at_least: Option<f64>,
    pub writes: Option<String>,
}

One question in the bank.

Fields

question: Question

The question.

options_from: Option<String>

For a choice: a state path (key or key.field.0) holding the options, read at each ask. Each array element is an option: a string, a number, or an object keyed by its id, value or name field.

none: Option<String>

For a choice: add NONE_OPTION with this description. A choice always picks something, so a question like “which offered time did the caller pick?” needs a way to say they have not.

at_least: Option<f64>

The P(true) (boolean) or certainty (choice, score) an answer needs.

writes: Option<String>

Write the decided value into this state key: the chosen option (an object option whole), the score, or the boolean. The question is then also asked whenever an active guard reads that key.

Implementations

impl Decision

pub fn new(question: Question) -> Self

A question with the defaults.

pub fn options_from(self, path: impl Into<String>) -> Self

Read a choice’s options from a state path.

pub fn or_none(self, description: impl Into<String>) -> Self

Add a “none of these” option meaning description.

pub fn at_least(self, threshold: f64) -> Self

Require this probability (boolean) or certainty (choice, score).

pub fn writes(self, key: impl Into<String>) -> Self

Write the decided value into key.

pub fn record_scripted( &self, id: &str, answer: &Value, state: &State, turn: &str, )

Record answer to question id for caller turn turn as if a decision model gave it with full certainty, writing what a live ask writes: true/false for a boolean, an option’s key for a choice (NONE_OPTION for none), a number for a score, anything else for unsure. For scripted conversations: offline scenarios and tests.

Trait Implementations
