    Type Alias ValidationChecks<T>

    ValidationChecks: {
        [K in keyof T]?: T[K] extends AstNode
            ? ValidationCheck<T[K]>
            | ValidationCheck<T[K]>[]
            : never
    } & { AstNode?: ValidationCheck<AstNode>
    | ValidationCheck<AstNode>[] }

    A utility type for associating non-primitive AST types to corresponding validation checks. For example:

      const checks: ValidationChecks<StatemachineAstType> = {
    State: validator.checkStateNameStartsWithCapital
    };

    If an AST type does not extend AstNode, e.g. if it describes a union of string literals, that type's name must not occur as a key in objects of type ValidationCheck<...>.

    Type Parameters

    • T

      a type definition mapping language specific type names (keys) to the corresponding types (values)
