* add derive(specta::Type) * use specta from git * introduce Uuid type * remove unnecessary specta::Type * document export_types test * upgrade Specta The previous Specta branch had some hacks that were just for this project. They have all been converted into proper features so they can be merged into main. * remove some unnecessary specta::Type uses * add MessageDiscriminantDef explanation * manually export types with specta * rename 'specta.rs' to 'export_types.rs' * rename 'export_types' to 'generate_ts_types' --------- Co-authored-by: Oscar Beaumont <oscar@otbeaumont.me>
