Naturals are bounded about dhall-rust HOT 5 CLOSED

I could yeah. But I'd rather wait until someone really needs to store a huge number, to understand what they really need.

It is indeed intentional. Haskell has built-in support for numbers of arbitrary size, but rust and the serde ecosystem don't. It would have been a lot of work for nothing since serde would have rejected it. Do you have a use for such huge numbers?

I personally don't, but I found this while writing tests for dhall-python, which is an implementation I maintain that depends on dhall-rust w/ FFI, since Python supports arbitrarily-sized numbers. I guess it's unfeasible to support arbitrarily large numbers while serde doesn't support it. Thanks for the info

We could probably add support for deserializing it as a u128, no?

Probably not actually, since it's being parsed as a u64 currently:
