Cargo Features

[dependencies]
http_router_alt = { version = "0.2.0", default-features = false, features = ["with_hyper"] }
default = with_hyper

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

with_hyper default = 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.
