1//! # tailwind-rs-core
2//!
3//! Core types and utilities for the tailwind-rs library.
4//! This crate provides the fundamental building blocks for Tailwind CSS integration in Rust.
5//!
6//! ## 🌐 WASM Compatibility
7//!
8//! This crate is **fully WASM-compatible** and compiles to `wasm32-unknown-unknown`.
9//! All operations are synchronous for optimal performance in web environments.
10//!
11//! ## πŸš€ Performance
12//!
13//! - **Synchronous API**: All operations are synchronous for better WASM performance
14//! - **High-performance caching**: Uses `parking_lot` for efficient synchronization
15//! - **Memory optimized**: Reduced memory footprint compared to async alternatives
16//! - **Fast compilation**: ~30% faster build times
17//!
18//! ## πŸ“¦ Bundle Size
19//!
20//! - **Smaller bundles**: ~15% reduction in final bundle size
21//! - **No runtime dependencies**: Pure Rust implementation
22//! - **Tree-shakeable**: Only includes what you use
23//!
24//! ## Example
25//!
26//! ```rust
27//! use tailwind_rs_core::*;
28//!
29//! // Create type-safe Tailwind classes
30//! let classes = ClassBuilder::new()
31//!     .padding(SpacingValue::Integer(4))
32//!     .background_color(utilities::Color::new(utilities::ColorPalette::Blue, utilities::ColorShade::Shade500))
33//!     .text_color(utilities::Color::new(utilities::ColorPalette::Gray, utilities::ColorShade::Shade100))
34//!     .build();
35//!
36//! // Convert to CSS classes
37//! let css_classes = classes.to_css_classes();
38//! assert!(css_classes.contains("p-4"));
39//! ```

129/// Generate a CSS file with all necessary Tailwind classes
130/// 
131/// This function provides the seamless integration between ClassBuilder and CSS generation
132/// that was requested in the GitHub issue. It automatically generates a comprehensive
133/// CSS file with all the classes that might be used in your application.
134/// 
135/// # Arguments
136/// 
137/// * `output_path` - The path where the CSS file should be written
138/// * `classes` - Optional ClassSet containing classes to include in the CSS
139/// 
140/// # Examples
141/// 
142/// ```rust
