//! Imports from `std` that would be polyfilled for `no_std` builds (see //! `src/polyfill/no_std`). //! //! This implementation is used when `std` is available and just imports the //! necessary items from `std`. For `no_std` builds, the file //! `src/polyfill/no_std` is used instead, which doesn't depend on the standard //! library.
