Cargo Features

[dependencies]
doapi = { version = "0.1.3", default-features = false, features = ["unstable", "debug", "lints", "nightly"] }
default = nightly

The nightly feature is set by default whenever doapi is added without default-features = false somewhere in the dependency tree.

unstable = lints, nightly
debug
lints unstable? = clippy, nightly
nightly default lints? unstable?

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.
