Cargo Features

cargo-options-serializable has no features set by default.

[dependencies]
cargo-options-serializable = { version = "0.8.0", features = ["serializable"] }
serializable = 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.
