//! The _directories_ crate is //! //! - a tiny library with a minimal API (3 structs, 4 factory functions, getters) //! - that provides the platform-specific, user-accessible locations //! - for finding and storing configuration, cache and other data //! - on Linux, Windows (≥ Vista) and macOS. //! //! The library provides the location of these directories by leveraging the mechanisms defined by //! //! - the [XDG base directory](https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) and the [XDG user directory](https://www.freedesktop.org/wiki/Software/xdg-user-dirs/) specifications on Linux, //!
