the irc crate Build Status Crates.io Downloads Docs

"the irc crate" is a thread-safe and async-friendly IRC client library written in Rust. It's compliant with RFC 2812, IRCv3.1, IRCv3.2, and includes some additional, common features from popular IRCds. You can find up-to-date, ready-to-use documentation online on docs.rs.

Built with the irc crate

the irc crate is being used to build new IRC software in Rust. Here are some of our favorite projects:

Getting Started

To start using the irc crate with cargo, you can add irc = "0.13" to your dependencies in your Cargo.toml file. The high-level API can be found in irc::client::prelude. You'll find a number of examples to help you get started in examples/, throughout the documentation, and below.

Using Futures

The release of v0.14 replaced all existing APIs with one based on async/await.

use irc::client::prelude::*;
use futures::prelude::*;

#[tokio::main]
async fn main() -> Result<(), failure::Error> {
    // We can also load the Config at runtime via Config::load("path/to/config.toml")
    let config = Config {
        nickname: Some("the-irc-crate".to_owned()),
        server: Some("chat.freenode.net".to_owned()),
        channels: Some(vec!["#test".to_owned()]),
        ..Config::default()
    };

    let mut client = Client::from_config(config).await?;
    client.identify()?;

    let mut stream = client.stream()?;

    while let Some(message) = stream.next().await.transpose()? {
        print!("{}", message);
    }

    Ok(())
}

Configuring IRC Clients

As seen above, there are two techniques for configuring the irc crate: runtime loading and programmatic configuration. Runtime loading is done via the function Config::load, and is likely sufficient for most IRC bots. Programmatic configuration is convenient for writing tests, but can also be useful when defining your own custom configuration format that can be converted to Config. The primary configuration format is TOML, but if you are so inclined, you can use JSON and/or YAML via the optional json_config and yaml_config features respectively. At the minimum, a configuration requires nickname and server to be defined, and all other fields are optional. You can find detailed explanations of the various fields on docs.rs.

Alternatively, you can look at the example below of a TOML configuration with all the fields:

owners = []
nickname = "user"
nick_password = "password"
alt_nicks = ["user_", "user__"]
username = "user"
realname = "Test User"
server = "chat.freenode.net"
port = 6697
password = ""
proxy_type = "None"
proxy_server = "127.0.0.1"
proxy_port = "1080"
proxy_username = ""
proxy_password = ""
use_tls = true
cert_path = "cert.der"
client_cert_path = "client.der"
client_cert_pass = "password"
encoding = "UTF-8"
channels = ["#rust", "#haskell", "#fake"]
umodes = "+RB-x"
user_info = "I'm a test user for the irc crate."
version = "irc:git:Rust"
source = "https://github.com/aatxe/irc"
ping_time = 180
ping_timeout = 10
burst_window_length = 8
max_messages_in_burst = 15
should_ghost = false
ghost_sequence = []

[channel_keys]
"#fake" = "password"

[options]
note = "anything you want can be in here!"
and = "you can use it to build your own additional configuration options."
key = "value"

You can convert between different configuration formats with convertconf like so:

cargo run --example convertconf -- -i client_config.json -o client_config.toml

Note that the formats are automatically determined based on the selected file extensions. This tool should make it easier for users to migrate their old configurations to TOML.
