How to bind this enumeration?

[akiross]

Hello,
I'm trying to use bindgen to produce some nice binding for a C API; in there, there's an enumeration that looks like this:

enum VariantType {
    TyInt, TyFloat, TyString
};

typedef struct _Variant {
    enum VariantType varType;
    struct {
        int iValue;
        float fValue;
        char sValue[100];
    } varValue;
} Variant;

This could be nicely done in Rust with

enum Variant {
    IValue(i32),
    FValue(f32),
    SValue(u8[100])
}

or something on these lines.

I tried using rustfield_enum() on this, but couldn't make it work. Also, I'd like to hide _Variant so I tried to use blocklist_type("_Variant"), but this leads to it being ignore before the variant is aliased and therefore the build fails.

Would it be possible to achieve something similar automatically with bindgen?
Thank you!
