1//! The core prelude
2//!
3//! This module is intended for users of core which do not link to std as well.
4//! This module is imported by default when `#![no_std]` is used in the same
5//! manner as the standard library's prelude.

7// No formatting: this file is nothing but re-exports, and their order is worth preserving.
