type JSObjectSetPropertyCallback = Option<unsafe extern "C" fn(ctx: JSContextRef, object: JSObjectRef, propertyName: JSStringRef, value: JSValueRef, exception: *mut JSValueRef) -> bool>;

@typedef JSObjectSetPropertyCallback @abstract The callback invoked when setting a property's value. @param ctx The execution context to use. @param object The JSObject on which to set the property's value. @param propertyName A JSString containing the name of the property to set. @param value A JSValue to use as the property's value. @param exception A pointer to a JSValueRef in which to return an exception, if any. @result true if the property was set, otherwise false. @discussion If you named your function SetProperty, you would declare it like this:

bool SetProperty(JSContextRef ctx, JSObjectRef object, JSStringRef propertyName, JSValueRef value, JSValueRef* exception);

If this function returns false, the set request forwards to object's statically declared properties, then its parent class chain (which includes the default object class).
