Cargo Features

[dependencies]
navig18xx = { version = "0.1.0", default-features = false, features = ["ui"] }
default = ui

The ui feature is set by default whenever navig18xx is added without default-features = false somewhere in the dependency tree.

ui default = n18ui

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.
