02:22 <strmpnk> Is there a reason I can make an FFI call that returns a Pointer[None] and that works but I can't wrap that in a single field struct? Does the FFI assume a returned struct is a pointer rather than immediate?

02:23 <strmpnk> I'm trying to add some type safety to some win32 api FFI calls with a MaybeHandle type. I can't use MaybePointer since they don't use 0 for the invalid value.

02:28 <strmpnk> I can write a wrapper around each call anyway but it'd be nice to tag things with this type to make it less error prone when writing the wrappers.

02:35 <strmpnk> Also, I found a crash in the compiler when calling embed on Pointer[None]. I haven't followed up with that yet but I'll try to create a small example this weekend.

03:01 <strmpnk> jemc, maybe you'd have an idea here (log from a moment ago): https://irclog.whitequark.org/ponylang/2018-03-11

03:10 <strmpnk> I wonder if this is an ABI issue. I would have assumed it would only involve the word-size of the struct (Only one USize involved here) but perhaps the FFI is interpreting this differently.

03:12 <strmpnk> I'll assume it's a windows calling convention or ABI thing for now.

20:32 <strmpnk> Outside of just knowing, is there a way to ask Pony for the size of a struct? These are common in some C APIs there the struct may have expanded fields over many versions, so intermediate code needs to know how many bytes to copy when propagating the value.

20:34 <SeanTAllen> I dont think so, but Benoit would certainly know better than I. That would be a useful addition I believe (assuming it doesnt exist)

23:22 <chasegeaton> Hi, I am trying to create an HTTPClient using `HTTPClient(NetAuth(env.root), SSLContext(), false)`, but I am getting an error saying that the type of env.root (AmbientAuth val | None val) is not a subtype of parameter AmbientAuth val. How can I pass env.root into NetAuth? Thanks!
