/**
 * Conversion functions
 * ====================
 *
 * There are two main directions of conversion:
 * - `inTargetType(...)`: Create a wrapper whose lifetime depends on the
 *   input. The wrapper has type `TargetType`.
 * - `toTargetType(...)`: Create a standalone object of type `TargetType` that
 *   corresponds to the input. The lifetime of the output does not depend on the
 *   lifetime of the input.
 * - `wrapIn(TargetType*, ...)`: Same as `inTargetType()`, but for `TargetType`
 *   that cannot be copied and/or moved efficiently, or when there are multiple
 *   output arguments.
 * - `convertTo(TargetType*, ...)`: Same as `toTargetType()`, but for
 *   `TargetType` that cannot be copied and/or moved efficiently, or when there
 *   are multiple output arguments.
 *
 * `wrapIn()` and `convertTo()` functions will take output arguments before
 * input arguments. Some of these functions might return a value to indicate
 * success or error.
 *
 * In converting or wrapping something as a Treble type that contains a
 * `hidl_handle`, `native_handle_t*` will need to be created and returned as
 * an additional output argument, hence only `wrapIn()` or `convertTo()` would
 * be available. The caller must call `native_handle_delete()` to deallocate the
 * returned native handle when it is no longer needed.
 *
 * For types that contain file descriptors, `inTargetType()` and `wrapAs()` do
 * not perform duplication of file descriptors, while `toTargetType()` and
 * `convertTo()` do.
