Enum JsonError 

pub enum JsonError {
    Undefined,
    NonFiniteNumber(Number),
    BigInt,
    Function,
}

An Any<A> shape Any::to_json does not (yet) know how to render.

Scoped deliberately: arrays and objects recurse (see Any::to_json), so every remaining gap here bottoms out at a scalar with no direct JSON counterpart — mvp-roadmap.md’s open question 2 (“does the MVP print DJS for those, or report an error?”) is left for later, so this reports an error rather than guessing at a representation.

to_json itself is hand-written Rust standing in for FJS-compiled logic — see nanvm/lib/todo/to-json-fjs-migration.md for the plan to retire it once fjs compile can reach fjs/media/json/serializer/module.f.mjs.
