Struct Choice 

#[non_exhaustive]
pub struct Choice {
    pub instructions: Option<Value>,
    pub criteria: IndexMap<String, Option<Value>>,
}

Pick one option from a set you define.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

instructions: Option<Value>

What the model should decide.

criteria: IndexMap<String, Option<Value>>

Option label → description (None is sent as null: an undescribed option).

Implementations

impl Choice

pub fn new(instructions: impl Into<Value>) -> Self

A choice with instructions and no options yet; add them with Choice::option.

pub fn from_labels<I, S>(instructions: impl Into<Value>, labels: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

A choice between undescribed labels.

pub fn option( self, label: impl Into<String>, description: impl Into<Value>, ) -> Self

Add an option with a description.

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

Add an option without a description.
