Cargo Features

[dependencies]
exhaustive = { version = "0.2.1", default-features = false, features = ["macros"] }
default = macros

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

macros default = exhaustive_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.
