 The syntax for creating structures takes into account C rules for aligning objects within a structure, and auxiliary comments help to automatically set the endianness of the field. Learn more about alignment [here](https://learn.microsoft.com/en-us/cpp/c-language/padding-and-alignment-of-structure-members) and [here](https://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Type-Attributes.html).
