You need to use the --all-features argument.

https://github.com/tokio-rs/tokio/blob/master/CONTRIBUTING.md#cargo-commands

Due to the extensive use of features in Tokio, you will often need to add extra arguments to many common cargo commands. This section lists some commonly needed commands.

Some commands just need the --all-features argument:

cargo build --all-features
cargo check --all-features
cargo test --all-features
