Crates

Twilight is, at heart, an ecosystem. These components of the ecosystem don't depend on each other in unnecessary ways, allowing you to pick and choose and combine the crates that you need for your use case. The crates for Twilight are categorised into three groups: the core crates, first-party crates, and third-party crates.

Core Crates

Twilight includes a few crates which are the "building blocks" to most peoples' use cases. You might not need them all, but generally speaking you'll need most of them. Most of them wrap Discord's various APIs.

• model: All of the structs, enums, and bitflags used by the Discord APIs.
• http: HTTP client supporting all of the documented features of Discord's HTTP API, with support for ratelimiting, proxying, and more.
• gateway: Clients supporting Discord's gateway API.
• cache: Definitions for implementing a cache. An in-process memory implementation is included.
• standby: Utility for asynchronously waiting for certain events, like a new message in a channel or a new reaction to a message.
• util: Provides various utilities for use with twilight such as: builders for larger structs, permissing calculator to calculate permission of members and various extension traits for snowflakes.

First-Party Crates

There are some first-party crates maintained by the Twilight organization, but not included in the core experience. These might be for more advanced or specific use cases or clients for third-party services. An example of a first-party crate is twilight-lavalink, a Client for interacting with Lavalink.

Third-Party Crates

Third-party crates are crates that aren't officially supported by the Twilight organization, but are recognised by it.
