Expand description
An error returned from the model
module.
This is always wrapped within the library’s Error::Model
variant.
Examples
Matching an Error
with this variant would look something like the
following for the GuildId::ban
method, which in this example is used to
re-ban all members with an odd discriminator:
use serenity::prelude::*; use serenity::model::prelude::*; use serenity::Error; use serenity::model::ModelError; struct Handler; #[serenity::async_trait] impl EventHandler for Handler { async fn guild_ban_removal(&self, context: Context, guild_id: GuildId, user: User) { // If the user has an even discriminator, don't re-ban them. if user.discriminator % 2 == 0 { return; } match guild_id.ban(&context, user, 8).await { Ok(()) => { // Ban successful. }, Err(Error::Model(ModelError::DeleteMessageDaysAmount(amount))) => { println!("Failed deleting {} days' worth of messages", amount); }, Err(why) => { println!("Unexpected error: {:?}", why); }, } } } let token = std::env::var("DISCORD_BOT_TOKEN")?; let mut client = Client::builder(&token).event_handler(Handler).await?; client.start().await?;
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
When attempting to delete below or above the minimum and maximum allowed number of messages.
DeleteMessageDaysAmount(u8)

has already been crossposted,
and cannot be crossposted twice.
An indication that you cannot crosspost a Message
.
