Cargo Features

rtest-util has no features set by default.

rtest-util = { version = "0.2.0", features = ["derive", "serde"] }
derive = darling, proc-macro2, quote

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.
