Cargo Features

EnumDowncast has no features set by default.

[dependencies]
enum_downcast = { version = "0.2.0", features = ["derive"] }
derive = enum_downcast_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.

enum_downcast_derive derive?
