Type Alias mozjs_sys::jsapi::JSWrapObjectCallback

pub type JSWrapObjectCallback = Option<unsafe extern "C" fn(arg1: *mut JSContext, arg2: HandleObject, arg3: HandleObject) -> *mut JSObject>;

Callback used to ask the embedding for the cross compartment wrapper handler that implements the desired prolicy for this kind of object in the destination compartment. |obj| is the object to be wrapped. If |existing| is non-nullptr, it will point to an existing wrapper object that should be re-used if possible. |existing| is guaranteed to be a cross-compartment wrapper with a lazily-defined prototype and the correct global. It is guaranteed not to wrap a function.
