++// 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
++
++// Aid in returning Operation from callbacks
