Cargo Features

certificate_manager has no features set by default.

[dependencies]
certificate_manager = { version = "0.2.0", features = ["full", "sign_cert"] }
full = actix-web, argh, rustls
sign_cert = argh

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.

actix-web full?
rustls full?
argh full? sign_cert?
