Enum OptionKind

    Number {
        default: Option<f64>,
        min: Option<f64>,
        max: Option<f64>,
    },
    Integer {
        default: Option<i64>,

    NumberList {
        default: Option<Vec<f64>>,
        min_len: Option<usize>,
        ascending: bool,
    },
    Choice {
        default: Option<String>,
        items: Vec<ChoiceItem>,
    },
    MultiChoice {
        default: Option<Vec<String>>,
        items: Vec<ChoiceItem>,
    },
}

Shape and bounds of one describable block option (spec §3.2.1).

Bounds and defaults are advisory — they tell a UI what to offer, and are never the validation authority. Production validates independently, so an engine may accept a value no descriptor advertised.

Variants

Number

Real number, with optional inclusive bounds.

Fields

default: Option<f64>

min: Option<f64>

max: Option<f64>

Integer

Whole number, with optional inclusive bounds.

Fields

default: Option<i64>

min: Option<i64>

max: Option<i64>

Boolean

Fields

default: Option<bool>

Text

Fields

default: Option<String>

NumberList

Ordered list of reals — threshold edges and the like.

Fields

default: Option<Vec<f64>>

min_len: Option<usize>

Fewest entries the block will accept, when it requires any.

ascending: bool

Whether entries must strictly ascend.

Choice

Exactly one of items.

Fields

default: Option<String>

items: Vec<ChoiceItem>

MultiChoice

Any subset of items.

Fields

default: Option<Vec<String>>

items: Vec<ChoiceItem>
