Cargo Features

Doku has no features set by default.

doku = { version = "0.21.1", features = ["chrono-04", "url-2"] }
chrono-04 = chrono
url-2 = url

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.

chrono chrono-04?
url url-2?
