Cache

Twilight includes an in-process-memory cache. It's responsible for processing events and caching things like guilds, channels, users, and voice states.

Examples

Process new messages that come over a shard into the cache:

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
use futures::StreamExt;
use std::env;
use twilight_cache_inmemory::InMemoryCache;
use twilight_gateway::{Intents, Shard};

let token = env::var("DISCORD_TOKEN")?;

let (shard, mut events) = Shard::new(token, Intents::GUILD_MESSAGES);
shard.start().await?;

let cache = InMemoryCache::new();

while let Some(event) = events.next().await {
    cache.update(&event);
}
    Ok(())
}
