[][src]Crate serenity

Serenity is a Rust library for the Discord API.

View the examples on how to make and structure a bot.

Serenity supports bot user authentication via the use of Client::builder.

Once logged in, you may add handlers to your client to dispatch Events, such as Client::on_message. This will cause your handler to be called when a Event::MessageCreate is received. Each handler is given a Context, giving information about the event. See the client's module-level documentation.

The Shard is transparently handled by the library, removing unnecessary complexity. Sharded connections are automatically handled for you. See the gateway's documentation for more information.

A Cache is also provided for you. This will be updated automatically for you as data is received from the Discord API via events. When calling a method on a Context, the cache will first be searched for relevant data to avoid unnecessary HTTP requests to the Discord API. For more information, see the cache's module-level documentation.

Note that, although this documentation will try to be as up-to-date and accurate as possible, Discord hosts official documentation. If you need to be sure that some information piece is sanctioned by Discord, refer to their own documentation.

Full Examples

Full examples, detailing and explaining usage of the basic functionality of the library, can be found in the examples directory.


Add the following to your Cargo.toml file:

serenity = "0.9"


pub use crate::client::Client;
pub use futures;



A set of builders used to make using methods on certain structs simpler to use.


A cache containing data received from Shards.


The Client contains information about a single bot's token, as well as event handlers. Dispatching events to configured handlers and starting the shards' connections are handled directly via the client. In addition, the http module and Cache are also automatically handled by the Client module for you.


Collectors will receive events from the contextual shard, check if the filter lets them pass, and collects if the receive, collect, or time limits are not reached yet.


A set of constants used by the library.


The framework is a customizable method of separating commands.


The gateway module contains the pieces - primarily the Shard - responsible for maintaing a WebSocket connection with Discord.


The HTTP module which provides functions for performing requests to endpoints in Discord's API.


Mappings of objects received from the API, with optional helper methods for ease of use.


A set of exports which can be helpful to use.


A set of utilities to help with common use cases that are not required to fully use the library.


A module for connecting to voice channels.





A common error enum returned by most of the library's functionality within a custom Result.



An extension trait for Futures that provides a variety of convenient adapters.
