Cargo Features

[dependencies]
js_option = { version = "0.1.1", default-features = false, features = ["serde"] }

default = serde

The serde feature is set by default whenever js_option is added without default-features = false somewhere in the dependency tree.

serde default = serde_crate

Features from optional dependencies
