+//! # The Rust Standard Library
+//!
+//! The Rust Standard Library is the foundation of portable Rust software, a
+//! set of minimal and battle-tested shared abstractions for the [broader Rust
+//! ecosystem][crates.io]. It offers core types, like [`Vec<T>`] and
+//! [`Option<T>`], library-defined [operations on language
+//! primitives](#primitives), [standard macros](#macros), [I/O] and
+//! [multithreading], among [many other things][other].
+//!
+//! `std` is available to all Rust crates by default. Therefore, the
+//! standard library can be accessed in [`use`] statements through the path
+//! `std`, as in [`use std::env`].
+//!
+//! # How to read this documentation
+//!
+//! If you already know the name of what you are looking for, the fastest way to
+//! find it is to use the <a href="#" onclick="focusSearchBar();">search
+//! bar</a> at the top of the page.
+//!
+//! Otherwise, you may want to jump to one of these useful sections:
+//!
+//! * [`std::*` modules](#modules)
+//! * [Primitive types](#primitives)
+//! * [Standard macros](#macros)
+//! * [The Rust Prelude]
+//!
+//! If this is your first time, the documentation for the standard library is
+//! written to be casually perused. Clicking on interesting things should
+//! generally lead you to interesting places. Still, there are important bits
+//! you don't want to miss, so read on for a tour of the standard library and
+//! its documentation!
+//!
+//! Once you are familiar with the contents of the standard library you may
+//! begin to find the verbosity of the prose distracting. At this stage in your
+//! development you may want to press the `[-]` button near the top of the
+//! page to collapse it into a more skimmable view.
+//!
+//! While you are looking at that `[-]` button also notice the `source`
+//! link. Rust's API documentation comes with the source code and you are
+//! encouraged to read it. The standard library source is generally high
+//! quality and a peek behind the curtains is often enlightening.
+//!
+//! # What is in the standard library documentation?
+//!
+//! First of all, The Rust Standard Library is divided into a number of focused
+//! modules, [all listed further down this page](#modules). These modules are
+//! the bedrock upon which all of Rust is forged, and they have mighty names
+//! like [`std::slice`] and [`std::cmp`]. Modules' documentation typically
+//! includes an overview of the module along with examples, and are a smart
+//! place to start familiarizing yourself with the library.
+//!
+//! Second, implicit methods on [primitive types] are documented here. This can
+//! be a source of confusion for two reasons:
+//!
+//! 1. While primitives are implemented by the compiler, the standard library
+//!    implements methods directly on the primitive types (and it is the only
+//!    library that does so), which are [documented in the section on
+//!    primitives](#primitives).
+//! 2. The standard library exports many modules *with the same name as
+//!    primitive types*. These define additional items related to the primitive
+//!    type, but not the all-important methods.
+//!
+//! So for example there is a [page for the primitive type
+//! `i32`](primitive::i32) that lists all the methods that can be called on
+//! 32-bit integers (very useful), and there is a [page for the module
+//! `std::i32`] that documents the constant values [`MIN`] and [`MAX`] (rarely
+//! useful).
+//!
+//! Note the documentation for the primitives [`str`] and [`[T]`][prim@slice] (also
+//! called 'slice'). Many method calls on [`String`] and [`Vec<T>`] are actually
+//! calls to methods on [`str`] and [`[T]`][prim@slice] respectively, via [deref
+//! coercions][deref-coercions].
+//!
+//! Third, the standard library defines [The Rust Prelude], a small collection
+//! of items - mostly traits - that are imported into every module of every
+//! crate. The traits in the prelude are pervasive, making the prelude
+//! documentation a good entry point to learning about the library.
+//!
+//! And finally, the standard library exports a number of standard macros, and
+//! [lists them on this page](#macros) (technically, not all of the standard
+//! macros are defined by the standard library - some are defined by the
+//! compiler - but they are documented here the same). Like the prelude, the
+//! standard macros are imported by default into all crates.

+//!
+//! # A Tour of The Rust Standard Library
+//!
+//! The rest of this crate documentation is dedicated to pointing out notable
+//! features of The Rust Standard Library.
+//!
+//! ## Containers and collections
+//!
+//! The [`option`] and [`result`] modules define optional and error-handling
+//! types, [`Option<T>`] and [`Result<T, E>`]. The [`iter`] module defines
+//! Rust's iterator trait, [`Iterator`], which works with the [`for`] loop to
+//! access collections.
+//!
+//! The standard library exposes three common ways to deal with contiguous
+//! regions of memory:
+//!
+//! * [`Vec<T>`] - A heap-allocated *vector* that is resizable at runtime.
+//! * [`[T; N]`][prim@array] - An inline *array* with a fixed size at compile time.
+//! * [`[T]`][prim@slice] - A dynamically sized *slice* into any other kind of contiguous
+//!   storage, whether heap-allocated or not.
+//!
+//! Slices can only be handled through some kind of *pointer*, and as such come
+//! in many flavors such as:
+//!
+//! * `&[T]` - *shared slice*
+//! * `&mut [T]` - *mutable slice*
+//! * [`Box<[T]>`][owned slice] - *owned slice*
+//!
+//! [`str`], a UTF-8 string slice, is a primitive type, and the standard library
+//! defines many methods for it. Rust [`str`]s are typically accessed as
+//! immutable references: `&str`. Use the owned [`String`] for building and
+//! mutating strings.
+//!
+//! For converting to strings use the [`format!`] macro, and for converting from
+//! strings use the [`FromStr`] trait.
+//!
+//! Data may be shared by placing it in a reference-counted box or the [`Rc`]
+//! type, and if further contained in a [`Cell`] or [`RefCell`], may be mutated
+//! as well as shared. Likewise, in a concurrent setting it is common to pair an
+//! atomically-reference-counted box, [`Arc`], with a [`Mutex`] to get the same
+//! effect.
+//!
+//! The [`collections`] module defines maps, sets, linked lists and other
+//! typical collection types, including the common [`HashMap<K, V>`].
+//!
+//! ## Platform abstractions and I/O
+//!
+//! Besides basic data types, the standard library is largely concerned with
+//! abstracting over differences in common platforms, most notably Windows and
+//! Unix derivatives.
+//!
+//! Common types of I/O, including [files], [TCP], [UDP], are defined in the
+//! [`io`], [`fs`], and [`net`] modules.
+//!
+//! The [`thread`] module contains Rust's threading abstractions. [`sync`]
+//! contains further primitive shared memory types, including [`atomic`] and
+//! [`mpsc`], which contains the channel types for message passing.
