//! # shdrlib - Three-Tier Vulkan Shader Compilation and Rendering Framework
//!
//! **A pure Rust Vulkan rendering library with a unique three-tier architecture** that lets you choose
//! your abstraction level: from bare-metal Vulkan control to high-level one-liners.

//!
//! ## 🎯 What Makes shdrlib Different?
//!
//! Unlike traditional graphics libraries that force you into one abstraction level, **shdrlib gives you three
//! tiers that work together seamlessly**:
//!
//! | Tier | Abstraction Level | Code Reduction | Use Case |
//! |------|------------------|----------------|----------|
//! | **CORE** | Thin Vulkan wrappers | Baseline (400 LOC) | Engines, frameworks |
//! | **EX** ⭐ | Explicit managers | **4-8x** (100 LOC) | Applications, games |
//! | **EZ** | High-level one-liners | **13x** (30 LOC) | Learning, prototyping |
//!
//! **All three tiers compile to identical machine code** - zero runtime cost!
//!
//! ---
//!
//! ## 🚀 Quick Start
//!
//! ### Installation
//!
//! ```toml
//! [dependencies]
//! shdrlib = "0.1.2"
//! ash = "0.38"  # For Vulkan types
//! ```
//!
//! ### Your First Triangle (30 Lines!)
//!
//! ```rust,no_run
//! use shdrlib::ez::*;
//!
//! fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     // One-liner setup
//!     let mut renderer = EzRenderer::new()?;
//!     
//!     // One-liner pipeline
//!     let pipeline = renderer.quick_pipeline(VERTEX_GLSL, FRAGMENT_GLSL)?;
//!     
//!     // Render!
//!     renderer.render_frame(|frame| {
//!         frame.bind_pipeline(pipeline);
//!         frame.draw(3, 1, 0, 0);
//!         Ok(())
//!     })?;
//!     
//!     Ok(())
//! }
//! # const VERTEX_GLSL: &str = "#version 450\nvoid main() {}";
//! # const FRAGMENT_GLSL: &str = "#version 450\nvoid main() {}";
//! ```
//!
//! **That's it!** You just rendered with Vulkan.
//!
//! ---
//!
//! ## 📚 The Three Tiers
//!
//! ### 🎯 EZ Tier - Perfect for Learning
//!
//! **Best for:** Prototyping, learning Vulkan, quick demos
//!
//! ```rust,no_run
//! use shdrlib::ez::*;
//!
//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
//! let mut renderer = EzRenderer::new()?;
//! let pipeline = renderer.quick_pipeline(VERT, FRAG)?;
//! # let vertex_data: Vec<f32> = vec![0.0; 9];
//! let vertices = renderer.create_vertex_buffer(&vertex_data)?;
//!
//! renderer.render_frame(|frame| {
//!     frame.bind_pipeline(pipeline);
//!     frame.draw(3, 1, 0, 0);
//!     Ok(())
//! })?;
//! # const VERT: &str = "#version 450\nvoid main() {}";
//! # const FRAG: &str = "#version 450\nvoid main() {}";
//! # Ok(())
//! # }
//! ```
//!
//! - ✅ **13x less code** than CORE tier
//! - ✅ Intelligent defaults
//! - ✅ Perfect for learning
//! - ✅ Hard to misuse
//!
//! ---
//!
//! ### ⭐ EX Tier - Recommended for Production
//!
//! **Best for:** Real applications, games, production code
//!
//! ```rust,no_run
//! use shdrlib::ex::*;
//! use shdrlib::core::ShaderStage;
//!
//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
//! // Explicit but ergonomic
//! let mut runtime = RuntimeManager::new(RuntimeConfig::default())?;
//! let device = runtime.device();
//! let mut shaders = ShaderManager::new(device)?;
//!
//! // Type-safe shader management
//! let vert_id = shaders.add_shader(VERT_SRC, ShaderStage::Vertex, "vert")?;
//! let frag_id = shaders.add_shader(FRAG_SRC, ShaderStage::Fragment, "frag")?;
//!
//! // Build pipeline with fluent API
//! let pipeline_id = shaders.build_pipeline(
//!     PipelineBuilder::new()
//!         .vertex_shader(shaders.get_shader(vert_id)?.handle(), "main")
//!         .fragment_shader(shaders.get_shader(frag_id)?.handle(), "main")
//!         .color_attachment_formats(vec![ash::vk::Format::R8G8B8A8_UNORM]),
//!     "my_pipeline"
//! )?;
//!
//! // Cleanup is automatic!
//! # const VERT_SRC: &str = "#version 450\nvoid main() {}";
//! # const FRAG_SRC: &str = "#version 450\nvoid main() {}";
//! # Ok(())
//! # }
//! ```
//!
//! - ✅ **4-8x less code** than CORE tier
//! - ✅ Type-safe resource IDs
//! - ✅ Automatic lifetime management
//! - ✅ Zero-cost abstractions
//! - ✅ Production-ready
//!
//! ---
//!
//! ### 🔧 CORE Tier - Maximum Control
//!
//! **Best for:** Engine development, custom frameworks
//!
//! ```rust,no_run
//! use shdrlib::core::*;
//!
//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
//! // Direct Vulkan control
//! let instance = Instance::new(InstanceCreateInfo::default())?;
//! let physical_devices = instance.enumerate_physical_devices()?;
//! let device = Device::new(&instance, physical_devices[0], DeviceCreateInfo::default())?;
//! let shader = Shader::from_glsl(&device, GLSL_SOURCE, ShaderStage::Vertex, "main")?;
//!
//! // You manage all lifetimes and resources
//! # const GLSL_SOURCE: &str = "#version 450\nvoid main() {}";
//! # Ok(())
//! # }
//! ```
//!
//! - ✅ Maximum control
//! - ✅ Zero overhead
//! - ✅ Direct Vulkan access
//! - ✅ Perfect for frameworks
//!
//! ---
//!
//! ## ✨ Key Features
//!
//! ### Pure Rust Shader Compilation
//!
//! No external build tools required! shdrlib uses [naga](https://docs.rs/naga) for pure Rust
//! GLSL → SPIR-V compilation:
//!
//! ```rust,no_run
//! use shdrlib::core::{Shader, ShaderStage, Device};
//!
//! # fn example(device: &Device) -> Result<(), Box<dyn std::error::Error>> {
//! let glsl_source = r#"
//!     #version 450
//!     layout(location = 0) in vec3 position;
//!     void main() {
//!         gl_Position = vec4(position, 1.0);
//!     }
//! "#;
//!
//! let shader = Shader::from_glsl(device, glsl_source, ShaderStage::Vertex, "main")?;
//! // Shader is now compiled to SPIR-V and ready to use!
//! # Ok(())
//! # }
//! ```
//!
//! ### Zero-Cost Abstractions
//!
//! All three tiers compile to **identical machine code**. The high-level abstractions completely
//! inline away - no runtime cost!
//!
//! ### Memory Safety
//!
//! Rust's ownership system prevents:
//! - ✅ Use-after-free bugs
//! - ✅ Double-free errors
//! - ✅ Null pointer dereferences
//! - ✅ Data races
//!
//! ### Progressive Disclosure
//!
//! Start high-level, drop down when you need control:
//!
//! ```rust,no_run
//! use shdrlib::ez::EzRenderer;
//!
//! # fn example() -> Result<(), Box<dyn std::error::Error>> {
//! let mut renderer = EzRenderer::new()?;
//!
//! // Access the EX tier when you need it
//! let runtime = renderer.runtime();
//! let device = runtime.device();
//!
//! // Or even drop to CORE tier
//! let vk_device = device.handle();
//! # Ok(())
//! # }
//! ```
