Cargo Features

[dependencies]
xkcd = { version = "0.3.0", default-features = false, features = ["nightly-testing", "hyper"] }
default = hyper

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

nightly-testing = clippy

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.
