+// A note about `wrapped` functions
+//
+// C FFI demands `unsafe extern fn(*mut pa_context, ...) -> i32`, etc,
+// but we want to allow such callbacks to be safe. This means no
+// `unsafe` or `extern`, and callbacks should be called with a safe
+// wrapper of `*mut pa_context`. Since the callback doesn't take
+// ownership, this is `&Context`. `fn wrapped<T>(...)` defines a
+// function that converts from our safe signature to the unsafe
+// signature.
+//
+// Currently, we use a property of Rust, namely that each function
+// gets its own unique type.  These unique types can't be written
+// directly, so we use generic and a type parameter, and let the Rust
+// compiler fill in the name for us:
+//
+// fn get_sink_input_info<CB>(&self, ..., _: CB, ...) -> ...
+//     where CB: Fn(&Context, *const SinkInputInfo, i32, *mut c_void)
+//
+// Because we aren't storing or passing any state, we assert, at run-time :-(,
+// that our functions are zero-sized:
+//
+//	assert!(mem::size_of::<F>() == 0);
+//
+// We need to obtain a value of type F in order to call it. Since we
+// can't name the function, we have to unsafely construct that value
+// somehow - we do this using mem::uninitialized. Then, we call that
+// function with a reference to the Context, and save the result:
+//
+//              |       generate value        ||  call it  |
+// let result = ::std::mem::uninitialized::<F>()(&mut object);
+//
+// Lastly, since our Object is an owned type, we need to avoid
+// dropping it, then return the result we just generated.
+//
+//		mem::forget(object);
+//		result
