Cargo Features

[dependencies]
rudo = { version = "0.9.0", default-features = false, features = ["journald", "macos"] }
default = journald

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

journald default = systemd
macos = oslog

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.

oslog mac macos?
