Cargo Features

unit-root has no features set by default.

[dependencies]
unit-root = { version = "0.6.0", features = ["unstable"] }
unstable = rand, rand_distr

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.

rand unstable?
rand_distr unstable?
