Exit code: 101 in Windows 11, Discord Bot

[Patatas8800]

Hi, I have a problem with my code :

Error :
thread 'main' panicked at src\main.rs:36:6:
Expected a token in the environment: NotPresent
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
error: process didn't exit successfully: `target\debug\Sugar.exe` (exit code: 101)

main.rs :

use std::env;

use serenity::{
    async_trait,
    model::{channel::Message, gateway::Ready},
    prelude::*,
    client::bridge::gateway::GatewayIntents,
    Client
};

const FEED_MESSAGE: &str = "
Vous nourrissez Sugar 🍗 *grumsh grumsh*";

const FEED_COMMAND: &str = "?feed";

struct Handler;

#[async_trait]
impl EventHandler for Handler {
    async fn message(&self, ctx: Context, msg: Message) {
        if msg.content == FEED_COMMAND {
            if let Err(why) = msg.channel_id.say(&ctx.http, FEED_MESSAGE).await {
                println!("Error sending message: {:?}", why);
            }
        }
    }

    async fn ready(&self, _: Context, ready: Ready) {
        println!("{} is connected", ready.user.name);
    }
}

#[tokio::main]
async fn main() {
    let token = std::env::var("DISCORD_TOKEN")
    .expect("Expected a token in the environment");

    let mut client = Client::builder(&token)
    .event_handler(Handler)
    .await
    .expect("Err creating client");

    if let Err(why) = client.start().await {
        println!("Client error: {:?}", why);
    }
}

(i'm not use "DISCORD_TOKEN" in my realy code)

Cargo.toml :

[package]
name = "Sugar"
version = "0.1.0"
authors = ["Patatas8800"]
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
tokio = { version = "0.2", features = ["macros"] }
serenity = { default-features = false, features = ["client", "gateway", "model", "rustls_backend"], version = "0.9.0-rc.1"}

You have not provided an environment variable with the discord bots token so the bot cannot start. I'm not sure if i'm right here because i don't use Windows but you should be able to set one temporarily with set DISCORD_TOKEN=bot_token, obviously substituting that for your actual bot token, or you can setup dotenvy or another tool to do this for you.

I am gratefull for your answer. But after I have execute your suggestion I have the same result.

Here is the list of all my error (I don't know if this will be useful) :

Your environment variable is not set correctly, please ensure you have set the variable to match what the program is looking for, in this case DISCORD_TOKEN.

The output you have provided doesn't provide anything else than what your original output did, if you still need help I would recommend you look up how environment variables work, alongside taking a look at the rust book, the problems you are encountering are far beyond the scope of serenity.
