From cd43aa2fcb37157ded7c44f9b72e184358afde8e Mon Sep 17 00:00:00 2001 From: Emmanuel Gil Peyrot Date: Tue, 17 Dec 2024 16:26:40 +0100 Subject: [PATCH] xmpp-parsers: Convert the Actor enum into a struct MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit XEP-0045 doesn’t specify what to do in the case the actor contains both a @jid and a @nick, so let’s not encode anything special about that here. In addition this converted it to use xso. Supersedes !196. Fixes #88. --- parsers/src/muc/user.rs | 113 ++++++++-------------------------------- 1 file changed, 21 insertions(+), 92 deletions(-) diff --git a/parsers/src/muc/user.rs b/parsers/src/muc/user.rs index adf45a2abc9982f9459348b3122840e77507b62d..5dda58b9374d61176108243ff4059e67eb2c122a 100644 --- a/parsers/src/muc/user.rs +++ b/parsers/src/muc/user.rs @@ -5,16 +5,11 @@ // License, v. 2.0.
