Cargo Features

twilight-interactions = { version = "0.15.2", default-features = false, features = ["derive"] }
default = derive

The derive feature is set by default whenever twilight-interactions is added without default-features = false somewhere in the dependency tree.

derive default = twilight-interactions-derive
