Struct TypeDefinitionCommon

pub struct TypeDefinitionCommon {
    pub derived_from: Vec<Expression>,
    pub holds_when: Vec<Expression>,
    pub conditioned_by: Vec<Expression>,
}

Represents common fields for all type definition phrases.

Fields

derived_from: Vec<Expression>

A set of instance expressions that generate automatic instances for some type.

holds_when: Vec<Expression>

A set of boolean expressions that filter all possible types in the positive (syntax sugar for Derived from over a type’s fields with When <expr>).

conditioned_by: Vec<Expression>

A set of boolean expressions that limits what instances may be derived by Derived from-rules and Holds when-rules, i.e., something is only derived if all Conditioned by-rules are true.
