pub trait RowKey {
type Key;
}Expand description
Maps a value written in a selection list to the type its field is filed
under, so a field is read back with the same value that selected it.
Carries no message of its own: it is reached both from a selection list
(where SelectionPart says what belongs in one) and from .get()
(where LookupKey says what can name a field), and each of those is the
accurate sentence in its position.
