//! Maildir mailbox-delete coroutine wrapping
//! [`io_maildir::maildir::delete::MaildirDelete`]: recursively removes
//! the mailbox directory under the [`MaildirStore`].
//!
//! # Example
//!
//! ```rust,ignore
//! use io_email::mailbox::maildir::delete::MaildirMailboxDelete;
//!
//! client.run(MaildirMailboxDelete::new(&client.store, "Archive")?)?;
//! ```
