Cargo Features

garcon has no features set by default.

[dependencies]
garcon = { version = "0.2.3", features = ["no_std", "async"] }

async = futures-util

Affects garcon::Waiter.async_wait

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.
