pub const FORMAT: u32 = 2;Expand description
The format of what travels, as this Sioul reads and writes it
(docs/database.md, “The format of what travels”). 1: as Sioul 0.0.4 and
every earlier one wrote it. 2: money lines, covers, mail rules, splits,
presets and time sessions each named by its own id (Keyed::ids);
pinned sites, routines, task kinds, days off, the words you added or took
away and the lighter days one each, where they travelled whole. Each
device says it in its entry (devices::Entry::format), and writes format
2 once every device in the sharing says it (format_open): an older
Sioul, which reads format 1 only, is never sent what it cannot read.
