//! Define backends using common libraries.
//!
//! Cursive doesn't print anything by itself: it delegates this job to a
//! backend library, which handles all actual input and output.
//!
//! This module defines the [`Backend`] trait, as well as a few implementations
//! using some common libraries. Each of those included backends needs a
//! corresonding feature to be enabled.
