/// Follow is a trait that allows us to access FlatBuffers in a declarative,
/// type safe, and fast way. They compile down to almost no code (after
/// optimizations). Conceptually, Follow lifts the offset-based access
/// patterns of FlatBuffers data into the type system. This trait is used
/// pervasively at read time, to access tables, vtables, vectors, strings, and
/// all other data. At this time, Follow is not utilized much on the write
/// path.
///
/// Writing a new Follow implementation primarily involves deciding whether
/// you want to return data (of the type Self::Inner) or do you want to
/// continue traversing the FlatBuffer.
/// FollowStart wraps a Follow impl in a struct type. This can make certain
/// programming patterns more ergonomic.
