Cargo Features

CommandGroup has no features set by default.

[dependencies]
command-group = { version = "5.0.1", features = ["with-tokio"] }
with-tokio = async-trait, tokio

Affects command-group::tokio

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

async-trait with-tokio?
tokio with-tokio?
