Cargo Features

[dependencies]
cross_platform_tun = { version = "0.1.5", default-features = false, features = ["async"] }
default = async

The async feature is set by default whenever cross_platform_tun is added without default-features = false somewhere in the dependency tree.

async default = byteorder, bytes, tokio, tokio-util

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.

tokio async
tokio-util async
bytes async
byteorder async
