Expand description

This trait is intended to be implemented by types which embody the content of a key for a particular sorted index collection.

Note:

Multiple types might be mappable into the key payload, and so implement this trait
This trait is only one way - from value into content
This trait uses a generic, because the same type might be usable as a key for multiple explicit substates
