Automate  

Automate is a low level and asynchronous rust library for interacting with the Discord API

DISCLAIMER: This crate is at its very early stage and does not have most functionalities a discord bot would need (no voice, and only channel manipulation operations). Please don't use this crate except for experimenting. The crate also only works in rust nightly.

Getting started

Automate is currently unstable and only works with Rust nightly. The minimum tested version and the one used in CI is nightly-2019-11-24. Refer to rust edition guide to learn how to switch to rust nightly.

In order to use Automate in your project, add the following line to your Cargo.toml under the [dependencies] section :

automate = "0.1.3"

You can then write the following in your main.rs. This simple example will respond Hello ! to any user posting a message in any channel while ignoring messages from bots. In order for this example to work, you need to define the DISCORD_API_TOKEN environment variable. You can create a bot and generate a token on Discord's developers portal.

struct MessageListener;

#[async_trait]
impl Listener for MessageListener {
    async fn on_message_create(&mut self, session: &Session, message: &MessageCreateDispatch) -> Result<(), Error> {
        let message = &message.0;

        if message.author.id != session.bot().id {
            let content = Some(format!("Hello {}!", message.author.username));

            session.create_message(message.channel_id, CreateMessage {
                content,
                ..Default::default()
            }).await?;
        }

        Ok(())
    }
}

fn main() -> Result<(), Error> {
    automate::setup_logging();

    Discord::new(&env::var("DISCORD_API_TOKEN").expect("API token not found"))
        .with_listener(Box::new(MessageListener))
        .connect_blocking()?;
}
