4//! Conversion methods for [`cursive`][]’s text style types.
5//!
6//! *Requires the `cursive` feature.*
7//!
8//! This module implements these conversions:
9//! - [`AnsiColor`][] to [`cursive::theme::BaseColor`][]
10//! - [`Color`][] to [`cursive::theme::Color`][]
11//! - [`Effect`][] to [`cursive::theme::Effect`][]
12//! - [`Style`][] to [`cursive::theme::Style`][]
13//! - [`StyledStr`][] and [`StyledString`][] to [`cursive::utils::markup::StyledString`][]
14//!
15//! # Example
16//!
17//! Rendering a string:
18//!
19//! ```
20//! let text = text_style::StyledStr::plain("test").bold();
21//! let mut s = cursive::dummy();
22//! s.add_layer(cursive::views::TextView::new(text));
23//! s.add_global_callback('q', |s| s.quit());
24//! s.run();
25//! ```
