Expand description

Create a iterator of shards.

Passing a primary config is required. Further customization of this config may be performed in the callback.

§Examples

Start 10 out of 10 shards and count them:

use std::{collections::HashMap, env, sync::Arc};
use twilight_gateway::{Config, Intents};

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

let config = Config::new(token.clone(), Intents::GUILDS);
let shards = twilight_gateway::create_iterator(0..10, 10, config, |_, builder| builder.build());

assert_eq!(shards.len(), 10);

§Panics

Panics if range contains values larger than total.

Panics if loading TLS certificates fails.
