Introduction

In this tutorial, we will explore how to build a Discord bot using Rust, as demonstrated in Ian Carey's video. This guide will provide you with a high-level overview and actionable steps to create your own bot. Whether you're a beginner in Rust or looking to enhance your programming skills, this tutorial will help you get started with bot development on Discord.

Step 1: Set Up Your Development Environment

Before you start coding, you need to have the Rust programming language installed and set up on your machine.

  • Install Rust
    • Visit the official Rust website at rust-lang.org and follow the installation instructions for your operating system.
    • Use the following command in your terminal to install Rust:
      curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
      

  • Verify Installation
    • Run the command rustc --version in your terminal to ensure that Rust is installed correctly.

Step 2: Create a New Rust Project

To start building your Discord bot, you need to create a new Rust project.

  • Create a Project
    • Open your terminal and navigate to the directory where you want to create your project.
    • Run the following command:
      cargo new discord_bot
      

  • Navigate to Project Directory
    • Change into your new project directory:
      cd discord_bot
      

Step 3: Add Dependencies

Your Discord bot will require specific dependencies to function properly.

  • Edit Cargo.toml
    • Open the Cargo.toml file in your project directory.
    • Add the following dependencies under the [dependencies] section:
      serenity = "0.9"  # Replace with the latest version
      
  • Save the File: Make sure to save your changes.

Step 4: Write the Bot Code

Now you can start writing the code for your Discord bot.

  • Open src/main.rs
    • This is where you will write your bot's main code.

  • Basic Bot Structure
    • Use the following code snippet to set up a basic bot:
      use serenity::client::Client;
      use serenity::prelude::*;
      
      struct Handler;
      
      #[serenity::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() {
          let token = "YOUR_DISCORD_BOT_TOKEN";
          let mut client = Client::builder(token)
              .event_handler(Handler)
              .await
              .expect("Error creating client");
      
          if let Err(why) = client.start().await {
              println!("Client error: {:?}", why);
          }
      }
      
  • Replace YOUR_DISCORD_BOT_TOKEN: Make sure to substitute this with your actual Discord bot token.

Step 5: Run Your Bot

With your code written, it's time to run your bot.

  • Run the Bot
    • In your terminal, execute the following command:
      cargo run
      

  • Test the Bot
    • Go to your Discord server and type !ping. The bot should respond with Pong!.

Conclusion

You have now successfully created a simple Discord bot using Rust! This tutorial covered setting up your environment, creating a Rust project, adding dependencies, writing the bot code, and running the bot.

Next Steps

  • Experiment with adding more commands to your bot.
  • Explore the Serenity documentation for advanced features and capabilities.
  • Consider deploying your bot to a cloud service for continuous availability.
