From 7ed2bea9b4ea4bbdd2b06f0ca13386f2c059b481 Mon Sep 17 00:00:00 2001 From: glendc Date: Wed, 15 Nov 2023 14:23:57 +0100 Subject: [PATCH 01/29] giant refactor: immutable services and impl traits - use 'impl Future' returns for trait contracts: prevents hidden requirments - refactor tower design around immutable services: easier to reason and use, more natural to use like this, makes it also more clear that user needs to handle state properly, prevents state keeping in service when not required and easier to integrate with other code bases in ecosystem (e.g. hyper) --- Cargo.toml | 1 -
