From 9c098f2368d48c28ed02d891ff7f2a9fcc84d5d5 Mon Sep 17 00:00:00 2001 From: Mathieu Desnoyers Date: Thu, 15 Apr 2021 13:25:51 -0400 Subject: [PATCH] run_filter callback takes const event parameter The event parameter of the run_filter callback should be const, because it should not be modified, only read.
