Use one trait for all cases; use constant case for structures

luojia65 · luojia65 · commit 0f9eac405b61 · 2022-07-10T17:30:08.000+08:00
Replace all use of upper cases into constant cases, rename variables
with full case names, reformat code

 ## [Unreleased]
 
+- Use constant case for structure names; internal rearrangements for
+  case conversation traits
 - Add new feature `feature_group` which will generate cfg attribute for
   every group name when it is on
