Cargo Features

Qutex has no features set by default.

[dependencies]
qutex = { version = "0.2.6", features = ["async_await"] }
async_await = futures03

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.
