How to wrap types not implementing the Copy trait?

[gbryant-arm]

NB: The problem detailed here does not cause any issue in the current state of rust-mbedtls.

bindgen exposes types from the vendor implementation, then some of them are "wrapped" in another type, for instance ssl_config types can be accessed through Config types:

rust-mbedtls/mbedtls/src/ssl/config.rs

Lines 88 to 95 in 9e06b8e

	define!(
	#[c_ty(ssl_config)]
	struct Config<'c>;
	const init: fn() -> Self = ssl_config_init;
	const drop: fn(&mut Self) = ssl_config_free;
	impl<'q> Into<ptr> {}
	impl<'q> UnsafeFrom<ptr> {}
	);

However this mapping mechanism doesn't seem to work for types that don't implement the Copy trait. The reason for that is the into_inner() function:

rust-mbedtls/mbedtls/src/wrapper_macros.rs

Lines 118 to 121 in 9e06b8e

	pub(crate) fn into_inner(self) -> ::mbedtls_sys::$inner {
	let inner = self.inner;
	::core::mem::forget(self);
	inner

As you can see, self.inner is moved, which is not allowed for types not implementing Copy.

How would you support such types?
What's the rationale behind wrapping the types exposed by bindgen?
