//! dialoguer is a library for Rust that helps you build useful small
//! interactive user inputs for the command line. It provides utilities
//! to render various simple dialogs like confirmation prompts, text
//! inputs and more.
//!
//! Best paired with other libraries in the family:
//!
//! * [indicatif](https://docs.rs/indicatif)
//! * [console](https://docs.rs/console)
//!
//! # Crate Contents
//!
//! * Confirmation prompts
//! * Input prompts (regular and password)
//! * Input validation
//! * Selections prompts (single and multi)
//! * Fuzzy select prompt
//! * Other kind of prompts
//! * Editor launching
//!
//! # Crate Features
//!
//! The following crate features are available:
//! * `editor`: enables bindings to launch editor to edit strings
//! * `fuzzy-select`: enables fuzzy select prompt
//! * `history`: enables input prompts to be able to track history of inputs
//! * `password`: enables password input prompt
//! * `completion`: enables ability to implement custom tab-completion for input prompts
//!
//! By default `editor` and `password` are enabled.
