//! Define the [`Config`] structure used to configure the [`generate`] function using a
//! [Tailwind-like configuration](https://tailwindcss.com/docs/configuration).
//!
//! # Example
//!
//! ```
//! use encre_css::{Config, config::DarkMode};
//!
//! let mut config = Config::default();
//!
//! // Toggles the dark mode using the class `.dark`
//! config.theme.dark_mode = DarkMode::new_class(".dark");
//!
//! // Defines some custom colors, they will be usable in the `text`, `bg`,
//! // `border`, etc utilities.
//! config.theme.colors.add("primary", "#d3198c");
//! config.theme.colors.add("secondary", "#fff");
//!
//! // Defines some custom screen breakpoints
//! config.theme.screens.add("tablet", "640px");
//! config.theme.screens.add("laptop", "1024px");
//! config.theme.screens.add("desktop", "1280px");
//!
//! let generated = encre_css::generate(
//!     ["tablet:dark:bg-primary"],
//!     &config,
//! );
//!
//! assert!(generated.ends_with(r#"@media (min-width: 640px) {
//!   .dark .tablet\:dark\:bg-primary {
//!     --en-bg-opacity: 1;
//!     background-color: rgb(211 25 140 / var(--en-bg-opacity));
//!   }
//! }"#));
//! ```
//!
//! The previous example is equivalent to the following TOML configuration file:
//!
//! <div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">[theme]</span>
//! dark_mode = { type = <span class="string">"class"</span>, class = <span class="string">".dark"</span> }
//! colors = { primary = <span class="string">"#d3198c"</span>, secondary = <span class="string">"#fff"</span> }
//! screens = { tablet = <span class="string">"640px"</span>, laptop = <span class="string">"1024px"</span>, desktop = <span class="string">"1280px"</span> }
//! </code></pre></div>
//!
