Known issues

gotchaTokio requires the `rt` or `rt-multi-thread` feature for the runtime (enabled by default).

fix

Add `tokio = { version = "1", features = ["rt-multi-thread"] }` to Cargo.toml if you disable default features.

affects: >=1.0.0

gotchaUsing `tokio::main` macro requires the `macros` feature (enabled by default).

fix

Ensure `macros` feature is enabled or use `#[tokio::main]` only with default features.

affects: >=1.0.0
