Serenity is a Rust library for the Discord API.
View the examples on how to use serenity's API. To make a bot with slash commands or text commands, see the poise framework built on top of serenity. To send and receive data from voice channels, see the songbird library.
Serenity supports bot login via the use of Client::builder
.
You may also check your tokens prior to login via the use of
validate_token
.
Once logged in, you may add handlers to your client to dispatch Event
s,
by implementing the handlers in a trait, such as EventHandler::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 accurate, refer to their docs.
A basic ping-pong bot looks like:
use std::env;
use serenity::async_trait;
use serenity::model::channel::Message;
use serenity::prelude::*;
struct Handler;
#[async_trait]
impl EventHandler for Handler {
async fn message(&self, ctx: Context, msg: Message) {
if msg.content == "!ping" {
if let Err(why) = msg.channel_id.say(&ctx.http, "Pong!").await {
println!("Error sending message: {why:?}");
}
}
}
}
#[tokio::main]
async fn main() {
// Login with a bot token from the environment
let token = env::var("DISCORD_TOKEN").expect("Expected a token in the environment");
// Set gateway intents, which decides what events the bot will be notified about
let intents = GatewayIntents::GUILD_MESSAGES
| GatewayIntents::DIRECT_MESSAGES
| GatewayIntents::MESSAGE_CONTENT;
// Create a new instance of the Client, logging in as a bot.
let mut client =
Client::builder(&token, intents).event_handler(Handler).await.expect("Err creating client");
// Start listening for events by starting a single shard
if let Err(why) = client.start().await {
println!("Client error: {why:?}");
}
}
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:
[dependencies]
serenity = "0.12"
tokio = { version = "1.21.2", features = ["macros", "rt-multi-thread"] }
Serenity's minimum supported Rust version (MSRV) is Rust 1.74.
We opt to keep MSRV stable on the current
branch. This means it will remain
unchanged between minor releases. Occasionally, dependencies may violate SemVer
and update their own MSRV in a breaking way. As a result, pinning their
versions will become necessary to successfully build Serenity using an older
Rust release.
The next
branch tracks the latest Rust release as its MSRV. This allows for
swift development as new languages features are stabilized, and reduces
technical debt in the long run. When a new major release is cut, the MSRV on
current
will be updated to that of next
, and we will commit to supporting
that MSRV until the following major release.
Features can be enabled or disabled by configuring the library through Cargo.toml:
[dependencies.serenity]
default-features = false
features = ["pick", "your", "feature", "names", "here"]
version = "0.12"
The default features are: builder
, cache
, chrono
, client
, framework
, gateway
,
http
, model
, standard_framework
, utils
, and rustls_backend
.
There are these alternative default features, they require to set default-features = false
:
native_tls_backend
instead of the default rustls_backend
.If you are unsure which to pick, use the default features by not setting default-features = false
.
The following is a full list of features:
native_tls_backend
instead of rustls_backend
.tracing
feature and uses tokio::task::Builder
to spawn tasks with names if RUSTFLAGS="--cfg tokio_unstable"
is set.chrono
crate to represent timestamps. If disabled, the time
crate is used instead.To enable all parts of the codebase, use the "full" feature.
For possibly more up-to-date information, check the Cargo.toml.
Serenity offers two TLS-backends, rustls_backend
by default, you need to pick
one if you do not use the default features:
If you want all of the default features except for cache
for example, you can
list all but that:
[dependencies.serenity]
default-features = false
features = [
"builder",
"chrono",
"client",
"framework",
"gateway",
"http",
"model",
"standard_framework",
"utils",
"rustls_backend",
]
version = "0.12"
If you use the native_tls_backend
and you are not developing on macOS or Windows, you will need:
If you want a quick and easy way to host your bot, you can use shuttle, a Rust-native cloud development platform that allows deploying Serenity bots for free.
