Cargo Features

[dependencies]
doip-rs = { version = "0.0.0", default-features = false, features = ["async", "client", "server"] }
default = client

The client feature is set by default whenever doip-rs is added without default-features = false somewhere in the dependency tree.

async = tokio
client default
server

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.
