Cargo Features

hashgood has no features set by default.

hashgood = { version = "0.4.0", features = ["paste"] }
paste = copypasta

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.
