Cargo Features

macroex = { version = "0.2.0", default-features = false, features = ["derive", "quote"] }
default = derive, quote

These default features are set whenever macroex is added without default-features = false somewhere in the dependency tree.

derive default = macroex-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.
