cannot find function `spawn` in crate `livekit_runtime`

[Thintin914]

Hello, first of all, thank you for the amazing work of LiveKit Rust support. I struggled to find a good rust realtime server-client sdk for weeks. I switched from AWS Gamelift to LiveKit to try something new.

I added livekit = "0.3.2" to my Cargo.toml. I think it cannot get tokio in livekit_runtime.

Is there a temporary fork to resolve this issue? The same issue also happened in #380.

livekit_runtime should use tokio if it's specified as a dependency in your Cargo.toml and livekit has its default features set. if you're using livekit-api directly, you need to add the signal-client-tokio feature to it. could you send your Cargo.toml?

[Thintin914]

I only list some crates that is related:

[dependencies]
tokio = { version = "1", features = ["full"]}

livekit = "0.3.2"
livekit-api = "0.3.2"

My Cargo.toml also has tokio because I need to use it elsewhere. I don't know if that might cause error.

please update livekit and livekit-api to the newest versions published on crates.io just now, they should fix the issue

[Thintin914]

Thank you for fixing the issue. I updated the crate version and it's fine now.

[dependencies]
livekit = "0.5.1"
livekit-api = "0.4.0"
