How do you actually use this library

If you use any example in a blank fresh project all i get is errors. Yes you can run the example but only when you are in the project. Try creating a new blank rust projekt, then add for example the code you provide under https://docs.rs/twitch_api/0.7.0-rc.7/twitch_api/ in the first example Get a channel:

code:

use twitch_api::helix::HelixClient;
use twitch_api::twitch_oauth2::{AccessToken, UserToken};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync + 'static>> {
    // Create the HelixClient, which is used to make requests to the Twitch API
    let client: HelixClient<reqwest::Client> = HelixClient::default();
    // Create a UserToken, which is used to authenticate requests.
    let token =
        UserToken::from_token(&client, AccessToken::from("mytoken"))
            .await?;

    println!(
        "Channel: {:?}",
        client.get_channel_from_login("twitchdev", &token).await?
    );

    Ok(())
}

dependencies (features all is because you cant be bothered to find the right dependency for a simple example):

[dependencies]
twitch_api = { version = "0.7.0-rc.7", features = ["all"] }
reqwest = { version = "0.12.8", features = ["json"] }
serde = "1"
serde_json = { version = "1" }
tokio = { version = "1.40.0", features = ["macros", "rt-multi-thread"] }

What ends up happening is the code does not compile and only complains about reqwest not implementing HttpClient.

If you try to use the code from the eventsub_websocket for example it gets even worse.

  1. You're missing the reqwest feature for twitch_api
  2. You're running into dependency mismatches. You want request 0.12, but twitch_api depends on 0.11. If you change your dependency from reqwest 0.12 to 0.11, your code compiles.

If you want to use a newer version of reqwest, you need to depend on twitch_api as a Git dependency:

[dependencies]
reqwest = "0.12"
tokio = { version = "1.40.0", features = ["macros", "rt-multi-thread"] }
twitch_api = { git = "https://github.com/twitch-rs/twitch_api/", features = [
    "all",
    "reqwest",
] }

# workaround for https://github.com/twitch-rs/twitch_api/issues/256
[patch.crates-io.twitch_types]
git = "https://github.com/twitch-rs/twitch_api"

CC @Emilgardis I think we should release a new version on crates.io. The last one (0.7.0-rc.7) is over one year old and a lot of features have been added since then. Maybe we can get a few PRs in before, but it's probably better if we prioritize releasing soon.

RasAllhague commented

Thanks for the quick response. Tested it and it works with the workaround.

This is something you should mention somewhere close to the examples as there is currently no way for a new user to find this.

Emilgardis commented

yes, let's release just a rc, do some prs then 0.7, we've been on this rc for way to long :3 @Nerixyz
