Signature

function null(): Struct<null, null>;

Accepts null only. Every other value fails with invalid_type. That includes undefined at the root or in an array or tuple; a missing object or record field reports missing_key instead.

This is not the .null() modifier. The modifier adds null to the values another struct accepts.
