/* This struct MUST have explicit padding fields to ensure that all padding is
* zeroed and the zeros get properly copied, even across API boundaries. This
* is ensured in two ways:
*
* - Bindgen is invoked with --explicit-padding and if a __bindgen_paddingN
* member ever crops up, that tells us we need to add an explicit member
* here.
*
* - There is a set of const asserts in nak/api.rs which ensure that all of
* the union fields are equal to NAK_SHADER_INFO_STAGE_UNION_SIZE.
* zeroed and the zeros get properly copied, even across API boundaries.
