This requires you to enable the `nightly` feature: ```toml [dependencies] mingling = { version = "...", features = ["nightly"] } ``` ## Features > [!WARNING] > The following features can only be used with the nightly toolchain, and are only guaranteed to compile, not to be stable or production-ready. > > If you need a stable development experience, please **do not use** the `nightly` feature!
