/**
* 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.
