//! ## Description
//!
//! A crate that performs mail client operations such as
//! - Hold an [`Envelope`] with methods convenient for mail client use. (see
//!   module [`email`])
//! - Abstract through mail storages through the [`MailBackend`] trait, and
//!   handle read/writes/updates through it. (see module [`backends`])
//! - Decode attachments (see module [`email::attachments`])
//! - Create new mail (see [`email::Draft`](email::compose::Draft))
//! - Send mail with an SMTP client (see module [`smtp`])
//! - Manage contacts (see module [`contacts`])
//! - Build thread structures out of a list of mail via their `In-Reply-To` and
//!   `References` header values (see module [`thread`])
//!
//! Other exports are
//! - Basic mail account configuration to use with [`backends`] (see module
//!   [`conf`])
//! - A `debug` macro that works like `std::dbg` but for multiple threads. (see
//!   [`debug` macro](debug!))
