While libraries such as nom and cookie-factory can provide good parsing and serializing, they require a lot of boilerplate code. If your goal is to simply parse a structure like you would do it in C, you would need to first declare the struct, then use the parse macro which requires writing every field twice, and a serialize macro which requires writing every field once again. This is fine for a few simple structures, but in a filesystem implementation, for example, you might end up declaring over 100 structs. In that case a more compact parsing crate would be useful. On the other hand, transmuting raw bytes into the structs doesn't support configurable endianness, and might be undefined behavior. sbp provides a quick-and-dirty way to compactly define binary structs for parsing and serializing.
