Cargo Features

[dependencies]
cao = { version = "0.1.2", default-features = false, features = ["dnspod", "curl_invailed_cert", "ureq"] }
default = dnspod, ureq

These default features are set whenever cao is added without default-features = false somewhere in the dependency tree.

dnspod default
curl_invailed_cert = curl

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.
