Cargo Features

API has no features set by default.

api = { version = "0.2.0", features = ["use-hyper"] }
use-hyper = hyper

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.
