Static member functions

[JCBurnside]

is there a way to declare a c++ opaque type with a static member? then have it translate to an associated function on the rust side? perhaps something like

#[cxx::bridge]
mod ffi {
    extern "C++" {
        type OpaqueType;
        impl OpaqueType {
            fn assoc_fun() -> RT;
        }
    }
}

with the c++ like

struct OpaqueType {
    // fields
    static RT assoc_fun();
};

What is the current workaround for this currently?

// Inside namespace named "Monero"
struct WalletManagerFactory
{
    // logging levels for underlying library
    enum LogLevel {
        LogLevel_Silent = -1,
        LogLevel_0 = 0,
        LogLevel_1 = 1,
        LogLevel_2 = 2,
        LogLevel_3 = 3,
        LogLevel_4 = 4,
        LogLevel_Min = LogLevel_Silent,
        LogLevel_Max = LogLevel_4
    };

    static WalletManager * getWalletManager();
    static void setLogLevel(int level);
    static void setLogCategories(const std::string &categories);
};

I want to call getWalletManager(). What does my `bridge.rs´ have to look like?

#[cxx::bridge(namespace = "Monero")]
pub mod ffi {
    unsafe extern "C++" {
        include!("monero-wrapper/monero/src/wallet/api/wallet2_api.h");

        type WalletManager;
        type WalletManagerFactory;

        #[namespace = "Monero::WalletManagerFactory"]
        fn getWalletManager() -> *mut WalletManager;
    }
}

Workaround is here: #464.

Basically, create a freestanding function that acts as a shim.
