Struct serenity::cache::Settings

#[non_exhaustive]
pub struct Settings {
    pub max_messages: usize,
}

Settings for the cache.

Examples

Create new settings, specifying the maximum number of messages:

use serenity::cache::Settings as CacheSettings;

let mut settings = CacheSettings::new();
settings.max_messages(10);

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_messages: usize

The maximum number of messages to store in a channel’s message cache.

Defaults to 0.
