+//! **Auto-adapting [`stdout`] / [`stderr`] streams**
+//!
+//! *A portmanteau of "ansi stream"*
+//!
+//! [`AutoStream`] always accepts [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code),
+//! adapting to the user's terminal's capabilities.
+//!
+//! Benefits
+//! - Allows the caller to not be concerned with the terminal's capabilities
+//! - Semver safe way of passing styled text between crates as ANSI escape codes offer more
+//! compatibility than most crate APIs.
+//!
+//! Available styling crates:
+//! - [anstyle](https://docs.rs/anstyle) for minimal runtime styling, designed to go in public APIs
+//! (once it hits 1.0)
+//! - [owo-colors](https://docs.rs/owo-colors) for feature-rich runtime styling
+//! - [color-print](https://docs.rs/color-print) for feature-rich compile-time styling
+//!
+//! # Example
+//!
+//! ```
+//! # #[cfg(feature = "auto")] {
+//! use anstream::println;
+//! use owo_colors::OwoColorize as _;
+//!
+//! // Foreground colors
+//! println!("My number is {:#x}!", 10.green());
+//! // Background colors
+//! println!("My number is not {}!", 4.on_red());
+//! # }
+//! ```
+//!
+//! And this will correctly handle piping to a file, etc

+/// This allows a program to terminate immediately and provide feedback

+///
+/// This macro is the perfect way to assert conditions in example code and in
+/// tests. `panic!` is closely tied with the `unwrap` method of both
+/// [`Option`][ounwrap] and [`Result`][runwrap] enums. Both implementations call
+/// `panic!` when they are set to [`None`] or [`Err`] variants.
+///
+/// When using `panic!()` you can specify a string payload, that is built using
+/// the [`format!`] syntax. That payload is used when injecting the panic into
+/// the calling Rust thread, causing the thread to panic entirely.
+///
+/// The behavior of the default `std` hook, i.e. the code that runs directly
+/// after the panic is invoked, is to print the message payload to
+/// `stderr` along with the file/line/column information of the `panic!()`
+/// call. You can override the panic hook using [`std::panic::set_hook()`].
+/// Inside the hook a panic can be accessed as a `&dyn Any + Send`,
+/// which contains either a `&str` or `String` for regular `panic!()` invocations.
+/// To panic with a value of another other type, [`panic_any`] can be used.
+///
+/// See also the macro [`compile_error!`], for raising errors during compilation.
+///
+/// # When to use `panic!` vs `Result`
+///
+/// The Rust language provides two complementary systems for constructing /
+/// representing, reporting, propagating, reacting to, and discarding errors. These
+/// responsibilities are collectively known as "error handling." `panic!` and
+/// `Result` are similar in that they are each the primary interface of their
+/// respective error handling systems; however, the meaning these interfaces attach
+/// to their errors and the responsibilities they fulfill within their respective
+/// error handling systems differ.
+///
+/// The `panic!` macro is used to construct errors that represent a bug that has
+/// been detected in your program. With `panic!` you provide a message that
+/// describes the bug and the language then constructs an error with that message,
+/// reports it, and propagates it for you.
+///
+/// `Result` on the other hand is used to wrap other types that represent either
+/// the successful result of some computation, `Ok(T)`, or error types that
+/// represent an anticipated runtime failure mode of that computation, `Err(E)`.
+/// `Result` is used alongside user defined types which represent the various
+/// anticipated runtime failure modes that the associated computation could
+/// encounter. `Result` must be propagated manually, often with the the help of the
+/// `?` operator and `Try` trait, and they must be reported manually, often with
+/// the help of the `Error` trait.
+///
+/// For more detailed information about error handling check out the [book] or the
+/// [`std::result`] module docs.
