Benno Lossin b9b88be046 rust: init: wrap type checking struct initializers in a closure ... In the implementation of the init macros there is a `if false` statement that type checks the initializer to ensure every field is initialized. Since the next patch has a stack variable to store the struct, the function might allocate too much memory on debug builds. Putting the struct into a closure that is never executed ensures that even in debug builds no stack overflow error is caused. In release builds this was not a problem since the code was optimized away due to the `if false`.
