Using the cache to get deleted / updated message info

[PierreEVEN]

Hi !
I'm moving my bot from discord.js to serenity-rs.
Discord.js allows me to get the content of the old message when a message is updated, as well as the content of deleted ones.
I guess this is only possible because discord.js uses the cache to retrieve this information, but I think it should be possible using serenity-rs.

Also, the old_if_available and the new values of the fn message_update(&self, ctx: Context, old_if_available: Option<Message>, new: Option<Message>, event: MessageUpdateEvent) event are always None.

Is it the expected behavior ? The fact these parameters are always None is rather suspicious but maybe I've missed something ?

(also I think I've enabled all the required intents)

Thanks in advance,

Pierre

Have you set a max_messages value in https://docs.rs/serenity/latest/serenity/cache/struct.Settings.html? If you do not, it defaults to caching no messages.

Well, that was exactly what I was searching for ^^
Thanks for your quick reply ! :)
