Cargo Features

truck-geotrait has no features set by default.

[dependencies]
truck-geotrait = { version = "0.4.0", features = ["derive"] }
derive = truck-derivers

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.
