From ff6da900a043310f09fdc3e42e56ef8bd120b109 Mon Sep 17 00:00:00 2001 From: Sergio Benitez Date: Thu, 2 May 2024 19:12:25 -0700 Subject: [PATCH] Migrate to 'tracing' for logging. This commit: - Remove all traces of 'log'. - Send all logs unedited via tracing. - Parses and propagate log_level. - Implements an initial formatting subscriber.
