Cargo Features

jnix has no features set by default.

[dependencies]
jnix = { version = "0.5.1", features = ["derive"] }
derive = jnix-macros

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.

jnix-macros derive?
