Struct Type Introspection crashing about odin HOT 2 CLOSED

I came back to the preload file again and noticed there are other types like map and dynamic_array which currently don't appear to be part of the language yet. Perhaps I just jumped the gun and the struct type info hadn't been properly implemented up to this point v0.0.6. If that is the case I apologize for opening an issue Bill.

from odin.

First, when casting a union to its subtype/tag, do:

newtype_info, ok := cast(^Type_Info.Struct) type_info_of_val(newtype);

This will return a boolean to check if it's valid. cast doesn't do any other checks (maybe I should make a raw_cast ).

Second, the kind of that type isn't a Type_Info.Struct but a Type_Info.Named. This means you want to get the base type of that Named type. This can be done manually or through the procedure type_info_base.

Third, check fmt.odin for a good exampe of what I mean.

Note: You don't need to do a manual dereference to get a struct's field as the language does an automatic one indirect dereference in those cases (as well as in the using cases). This is help with refactoring, and logic.

x: ^Foo;
// These two are identical in outputted code
x.^bar = 123;
x.bar = 123;
