Crate list_features

Returns the list of enable features when building your crate.

The list_enabled_as_string function lists enabled features during the Cargo build process, in a format that can be directly saved in build artifacts, which can be then included elsewhere in the program and read at run time.

Other functions are made available in case you prefer obtaining intermediate data or want to provide more parameters, but they’re probably not what you’re looking for.

Examples
