Enum Question 

pub enum Question {
    Noul {
        instructions: String,
        criteria: Option<NoulCriteria>,
    },
    Choice {
        instructions: String,
        criteria: BTreeMap<String, String>,
    },
    Score {
        instructions: String,
        levels: Vec<String>,
    },
}

One typed question.

Variants

Noul

Yes/no. criteria optionally describes the two outcomes.

Fields

instructions: String

criteria: Option<NoulCriteria>

Choice

One of 2..=255 named options; the map value is the option’s description.

Fields

instructions: String

criteria: BTreeMap<String, String>

Score

Ordered 2..=10 levels, index 0 = lowest.

Fields

instructions: String

levels: Vec<String>

Implementations

impl Question

pub fn noul(instructions: impl Into<String>) -> Self

A yes/no question with no outcome descriptions.

pub fn choice<K: Into<String>, D: Into<String>>( instructions: impl Into<String>, options: impl IntoIterator<Item = (K, D)>, ) -> Self

A choice over (key, description) options.

pub fn score<L: Into<String>>( instructions: impl Into<String>, levels: impl IntoIterator<Item = L>, ) -> Self

A score over ordered levels, lowest first.

pub fn kind(&self) -> &'static str

The wire type: "noul", "choice" or "score".

pub fn instructions(&self) -> &str

pub fn validate(&self, id: &str) -> Result<(), DecideError>

DEC-E006 unless the question is askable: non-empty instructions, 2..=255 non-empty option keys, 2..=10 levels.

pub fn to_wire(&self) -> Value

The wire form: criteria is an object for noul/choice and an ARRAY of levels for score.

pub fn from_wire(id: &str, v: &Value) -> Result<Self, DecideError>

Parse one wire question. Shape faults are DEC-E006; the counts are checked too (this calls Question::validate).

Trait Implementations
