//! ## Features
//!
//! - `i32` newtype for exit codes
//! - Can represent any valid exit code
//! - Type safe, operations are restricted to what is valid for exit codes
//! - Includes common exit codes and signal exit codes
//! - Integrate with `main`, `std::process`, and `std::io::Error`
//! - Supports exiting silently (error message reported through another means)
//!
//! ## Install
//!
//! Add to your `Cargo.toml`:
//!
//! ```console
//! $ cargo add proc-exit
//! ```
//!
//! # Example
//!
//! ```
//! use proc_exit::prelude::*;
//!
//! fn main() {
//! // Simple but Macro-less `main`
//! // - Fast compiles
//! // - Composable with other features
//! let result = run();
//! proc_exit::exit(result);
//! }
//!
//! fn run() -> proc_exit::ExitResult {
//! // Integrates directly with `std::io::Error`, returning the right exit code.
//! let exit_status = std::process::Command::new("true")
//! .status().with_code(proc_exit::Code::FAILURE)?;
//! // Can pass `Command` exit codes right up, when appropriate
//! proc_exit::Code::from_status(exit_status).ok()?;
//!
//! proc_exit::Code::SUCCESS.ok()
//! }
//! ```
//!
//! ## Relevant CLI crates
//!
//! Other crates that might be useful in testing command line programs.
//! - [duct][duct] for orchestrating multiple processes.
//! - or [commandspec][commandspec] for easier writing of commands
//! - [rexpect][rexpect] for controlling interactive programs.
//! - [`assert_cmd`][assert_cmd] can be reused to simplify controlling CLIs

//! - [exitfailure][exitfailure]
//! - Allows `Display`able errors to be used with [`?` in `main()`](https://github.com/rust-lang/rust/issues/43301)
