there is no reactor running, must be called from the context of a Tokio 0.2.x runtime

[GabeDuarteM]

I'm trying to run the tokio example, but whenever we hit the line let mut runner = AsyncRunner::connect(connector, &user_config).await?; (https://github.com/museun/twitchchat/blob/master/examples/tokio_demo.rs#L20), I get the following error:

thread 'main' panicked at 'there is no reactor running, must be called from the context of a Tokio 0.2.x runtime', [home]/.cargo/registry/src/github.com-1ecc6299db9ec823/tokio-0.2.25/src/io/driver/mod.rs:203:30
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

my Cargo.toml has tokio = { version = "1.20.1", features = ["rt-multi-thread", "macros"] }, but if I change the version to 0.2.25 to match the runtime said on the error, I then get the following (it changes to Tokio 1.x runtime instead of Tokio 0.2.x runtime):

thread 'main' panicked at 'there is no reactor running, must be called from the context of a Tokio 1.x runtime', [home]/.cargo/registry/src/github.com-1ecc6299db9ec823/hyper-0.14.20/src/client/connect/dns.rs:121:24
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I'm new to rust, so this might be trivial, but I have no idea which other packages might be using tokio, and also not sure downgrading it is the best approach (I'd prefer to use the latest version, if possible)

My full Cargo.toml:

[package]
name = "thing"
version = "0.1.0"
edition = "2021"

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

[dependencies]
dotenv = "0.15.0"
reqwest = "0.11.11"
tokio = { version = "0.2.25", features = ["macros"] }
twitchchat = { version = "0.14.8", features = ["async", "tokio", "tokio-util"] }
twitch_oauth2 = { version = "0.7.0", features = ["reqwest"] }

anyhow = "1.0.59"
serde = "1.0.143"
serde_json = "1.0.83"

Is this really only solvable by downgrading all the packages until they all use the same tokio version?

I can perhaps push an update to upgrade to tokio 1.0, this crate has been in basically dormant mode for a while now.

But you can still use this crate without tokio -- just as the parser/encoder/decoder.

you should be able to use the current master branch for tokio 1

twitchchat = { git = "https://github.com/museun/twitchchat", version = "0.14.8", features = ["async", "tokio", "tokio-util"] }
