Crate serenity [−] [src]
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::new
.
Once logged in, you may add handlers to your client to dispatch Event
s,
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.
Example Bot
A basic ping-pong bot looks like:
#[macro_use] extern crate serenity; use serenity::client::Client; use serenity::prelude::EventHandler; use serenity::framework::standard::StandardFramework; use std::env; struct Handler; impl EventHandler for Handler {} fn main() { // Login with a bot token from the environment let mut client = Client::new(&env::var("DISCORD_TOKEN").expect("token"), Handler); client.with_framework(StandardFramework::new() .configure(|c| c.prefix("~")) // set the bot's prefix to "~" .on("ping", ping)); // start listening for events by starting a single shard let _ = client.start(); } command!(ping(_context, message) { let _ = message.reply("Pong!"); });
Full Examples
Full examples, detailing and explaining usage of the basic functionality of the
library, can be found in the examples
directory.
Installation
Add the following to your Cargo.toml
file:
[dependencies]
serenity = "0.4"
and to the top of your main.rs
:
#[macro_use] extern crate serenity;

Modules
builder |
A set of builders used to make using methods on certain structs simpler to use. |
cache |
A cache of events received over a |
client |
The Client contains information about a single bot or user'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 |
constants |
A set of constants used by the library. |
framework |
The framework is a customizable method of separating commands. |
gateway |
The gateway module contains the pieces - primarily the |
http |
The HTTP module which provides functions for performing requests to endpoints in Discord's API. |
model |
Mappings of objects received from the API, with optional helper methods for ease of use. |
prelude |
A set of exports which can be helpful to use. |
utils |
A set of utilities to help with common use cases that are not required to fully use the library. |
Macros
command |
A macro to generate "named parameters". This is useful to avoid manually using the "arguments" parameter and manually parsing types. |
Structs
CACHE |
A mutable and lazily-initialized static binding. It can be accessed across any function and in any context. |
Enums
Error |
A common error enum returned by most of the library's functionality within a
custom |
Type Definitions
Result |
The common result type between most library functions. |
