twilight-cache-inmemory

twilight-cache-inmemory is an in-process-memory cache for the [twilight-rs] ecosystem. It's responsible for processing events and caching things like guilds, channels, users, and voice states.

Features

By default no feature is enabled.

permission-calculator

The permission-calculator feature flag will bring in support for the PermissionCalculator; an API for calculating permissions through it is exposed via InMemoryCache::permissions. Support for calculating the permissions of a member on a root guild-level and in a guild channel is included.

Refer to the permission module for more documentation.

Examples

Update a cache with events that come in through the gateway:

use std::env;
use futures::stream::StreamExt;
use twilight_cache_inmemory::InMemoryCache;
use twilight_gateway::{Intents, Shard};

# #[tokio::main] async fn main() -> Result<(), Box<dyn std::error::Error>> {
let token = env::var("DISCORD_TOKEN")?;
let (shard, mut events) = Shard::new(token, Intents::GUILD_MESSAGES);
shard.start().await?;

// Create a cache, caching up to 10 messages per channel:
let cache = InMemoryCache::builder().message_cache_size(10).build();

while let Some(event) = events.next().await {
// Update the cache with the event.
cache.update(&event);
}
# Ok(()) }
