* start to implement apub inbox routing lib * got something that almost works * it compiles! * implemented some more * move library code to separate crate (most of it) * convert private message handlers * convert all comment receivers (except undo comment) * convert post receiver * add verify trait * convert community receivers * add cc field for all activities which i forgot before * convert inbox functions, add missing checks * convert undo like/dislike receivers * convert undo_delete and undo_remove receivers * move block/unblock activities * convert remaining activity receivers * reimplement http signature verification and other checks * also use actor type for routing, VerifyActivity and SendActivity traits * cleanup and restructure apub_receive code * wip: try to fix activity routing * implement a (very bad) derive macro for activityhandler * working activity routing! * rework pm verify(), fix tests and confirm manually also remove inbox username check which was broken * rework following verify(), fix tests and test manually * fix post/comment create/update, rework voting * Rewrite remove/delete post/comment, fix tests, test manually * Rework and fix (un)block user, announce, update post * some code cleanup * rework delete/remove activity receivers (still quite messy) * rewrite, test and fix add/remove mod, update community handlers * add docs for ActivityHandler derive macro * dont try to compile macro comments
