Cargo Features

[dependencies]
rsv = { version = "1.3.3", default-features = false, features = ["auto_sudo"] }
default = auto_sudo

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

auto_sudo default = sudo

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.

sudo auto_sudo

Enables sudo ^0.5.0
