error: no rules expected the token `;`

[fejfighter]

I seem to be having trouble incorporating the example code into a toy project I am playing with to learn a bit of rust.

Not sure what he cause is, but I'm on 1.64 on fedora if that makes much of a difference

Something is wrong with your tokio::select! I guess. I can't reproduce it. Can you share your Cargo.toml?

[fejfighter]

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

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

[dependencies]
google-gmail1 = "4.0.1+20220228"

hyper-tls = "0.5.0"
hyper-rustls = "0.23.0"

tokio = { version = "~1.2", features = [
    "macros",
    "io-util",
    "rt",
    "rt-multi-thread",
    "fs",
] }
futures-util = "0.3.24"
tokio-rustls = "0.23.4"
rustls = "*"
rustls-pemfile = "1.0.1"

[dependencies.async-std]

features = ["attributes"]

Sorry, I have been AFK for the last few days, there's a heap of extra stuff there because in the interest of progress/experimentation I have hacked something together short term with hyper.

from what you have suggested I might be missing a feature flag in tokio?

[programatik29]

Found the problem. It seems like tokio added biased option (which axum-server use) in version 1.4 and you are forcing to use version 1.2.

A slight oversight on my part. I should put tokio dependency to version 1.4 instead of 1.

[fejfighter]

Awesome, that works for me.

Not 100% sure why I had 1.2, probably from some tutorial/quick start I was looking at.

closing as this seems to fix the issue
