From 929b38e8ae4d61340cbd70352663af8f6f2418cf Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Mon, 5 Apr 2021 22:09:31 +0200 Subject: refactor(web/converse): Refactor first handlers to rouille This commit starts the refactoring process towards dropping actix (and tokio, ...). It builds, but at this commit, Converse does *not* work. I decided to commit to avoid more ridiculous diffs. Included changes: * Added dependency on rouille. * Refactored DbExecutor (formerly actix actor) to simply be a type with a few methods. Most actor messages still exist as they are being referred to by handlers. * Started refactoring two of the handlers (and their related renderer functions) into Rouille's call scheme. Important note: Rouille does not have safe session management out of the box, and it will need to be implemented as this progresses.
