You must initialize all record fields explicitly, however you can create a Static Factory method that will give you a fresh instance.
#light
type Info =
{
mutable A:uint64
mutable B:double
}
static member Create() = { A = 0UL; B = 0.0 }
let instanceOfInfo = Info.Create()

Built with WebSharper |
I'm calling a DLLImport function that will fill in a structure for me (passed by ref, can I?). So I create a structure in F#
type Info = {
mutable a:uint64
mutable b:double
<quite a few fields>
}
Now I'd like to just write
let info = Info // this line does not compile already
function(info)
What do I do? Do I actually have to initialize all the fields with some junk? Write a constructor? Thanks
