Cargo Features

[dependencies]
http-request-uri = { version = "0.2.1", default-features = false, features = ["http"] }
default = http

The http feature is set by default whenever http-request-uri is added without default-features = false somewhere in the dependency tree.

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.
