Raw Blame History

From a71f3ec3e0960d1a52997603a06fa9cc4ad08c06 Mon Sep 17 00:00:00 2001
From: Bastien Orivel <eijebong@bananium.fr>
Date: Tue, 29 May 2018 12:33:02 +0200
Subject: [PATCH] Update quote and proc-macro.
I give up on the doc comments. This is a rebase of #1334 keeping the formatting
of the comments and using TokenStream::from_str instead because one can hope.
Fixes #1407.
