Module fam

Trait and wrapper for working with C defined FAM structures.

In C 99 an array of unknown size may appear within a struct definition as the last member (as long as there is at least one other named member). This is known as a flexible array member (FAM). Pre C99, the same behavior could be achieved using zero length arrays.

Flexible Array Members are the go-to choice for working with large amounts of data prefixed by header values.

For example the KVM API has many structures of this kind.
