Shouldn't we be allowed to assign anything to `unknown`?
I have have a BSON parser that can fail when an attempt is made to parse a leaf into an expected structure. let’s say the BSON parse expects an int at a leaf, but it sees something else (e.g., a...

why don’t you use the type of the unparsed BSON for the payload of this exception?

Yeah this is a major pain. The reason for this being the way it is is that the compiler is not designed to continue when it encounters a type error. This is because it wouldn’t be able to type check...

this is absolutely a fair point that i should consider, although i also have this: let anyOrThrow = obj => switch any(obj) { | Some(o) => o | None => throw(InvalidValue(Obj.magic(obj))) } as...

although i agree it would be a nice qol improvement, i never found it to be a major pain. only seeing the next error is fine, because you fix it, and then you immediately see the next anyway. go to...

well this definitely calls for an Obj.magic anyway ^^

this looks like a good use case for meta programming, I’m pretty sure you could generate the variant from the record type using @rescript/tools for example!

I could certainly try that – It looks like rescript tools is vs-code thing primarily? I use Emacs mostly. You definitely could do something with a ppx-type thing. However, doesn’t it seem like it...

tbh, this should be included in the rescript stdlib as a sort of spec to guarantee object shapes on the ffi boundary with automatic checks.
View ArticleWelcome Sury - successor of ReScript Schema
I’d say Sury is a little bit too opinionated to be a part of the Stdlib. It’s more like a framework, which you install anyway if you need it. Also, there’s a really nice way to pattern-match on JSON...
