Cargo Features

us-state-info = { version = "0.2.4", features = ["serde1", "serde_abbreviation"] }
serde1 = serde
serde_abbreviation = serde

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.
