Module unread 

Where a reader’s unread lines start.

A conversation the reader comes back to marks the first line they had not read when they opened it, with a rule and “New messages” over it: the place to start reading again, kept while they read on, so lines arriving meanwhile do not move it. The app decides which line that is (from its read marks); the face is the same in every conversation.

Structs

UnreadDivider

UnreadDividerProps, built: an unread divider over a row.

UnreadDividerFace

The “New messages” divider: a rule across the column, its label at the trailing end, a list row tall like a day divider (super::DayDividerFace).

UnreadDividerProps

The divider as a widget, for a list built of widgets: a band across its column with its label at the trailing end, over the first line the reader had not read.
