Cargo Features

Todo-app-server has no features set by default.

[dependencies]
todo_app_server = { version = "0.1.3", features = ["tls"] }
tls = rustls

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.
