    Variable ConstructibleSchemaConst

    ConstructibleSchema: ZodCustom<Constructor, Constructor> = ...

    A Zod schema that validates JavaScript constructible functions.

    This schema validates values that can be used as constructors, including ES6 classes, traditional constructor functions, and built-in constructors. It uses the isConstructible guard function to determine if a value can be invoked with the new operator to create object instances.

    class MyClass {}
    function MyConstructor() {}

    ConstructibleSchema.parse(MyClass); // ✓ Valid
    ConstructibleSchema.parse(MyConstructor); // ✓ Valid
    ConstructibleSchema.parse(Array); // ✓ Valid
    ConstructibleSchema.parse(Date); // ✓ Valid
    ConstructibleSchema.parse(() => {}); // ✗ Throws validation error
    ConstructibleSchema.parse({}); // ✗ Throws validation error

    import { createAssertion, use } from 'bupkis';
    import { ConstructibleSchema } from 'bupkis/schema';

    const classAssertion = createAssertion(
      [ConstructibleSchema, 'to be a subclass of Error'],
      ConstructibleSchema.refine(
        (subject) => subject.prototype instanceof Error,
      ),
    );

    const { expect } = use([classAssertion]);
    expect(class MyError extends Error {}, 'to be a subclass of Error');
