Cargo Features

j-api has no features set by default.

[dependencies]
j-api = { version = "0.1.0", features = ["derive"] }
derive = j-api-derive

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.

j-api-derive derive?
