//! A pipeline that performs graphics processing operations.
//!
//! Unlike a compute pipeline, which performs general-purpose work, a graphics pipeline is geared
//! specifically towards doing graphical processing. To that end, it consists of several shaders,
//! with additional state and glue logic in between.
//!
//! A graphics pipeline performs many separate steps, that execute more or less in sequence.
//! Due to the parallel nature of a GPU, no strict ordering guarantees may exist.
//!
//! 1. Vertex input and assembly: vertex input data is read from data buffers and then assembled
//! into primitives (points, lines, triangles etc.).
//! 2. Vertex shader invocations: the vertex data of each primitive is fed as input to the vertex
//! shader, which performs transformations on the data and generates new data as output.
//! 3. (Optional) Tessellation: primitives are subdivided by the operations of two shaders, the
//! tessellation control and tessellation evaluation shaders. The control shader produces the
//! tessellation level to apply for the primitive, while the evaluation shader postprocesses the
//! newly created vertices.
//! 4. (Optional) Geometry shading: whole primitives are fed as input and processed into a new set
//! of output primitives.
//! 5. Vertex post-processing, including:
//! - Clipping primitives to the view frustum and user-defined clipping planes.
//! - Perspective division.
//! - Viewport mapping.
//! 6. Rasterization: converting primitives into a two-dimensional representation. Primitives may be
//! discarded depending on their orientation, and are then converted into a collection of
//! fragments that are processed further.
//! 7. Fragment operations. These include invocations of the fragment shader, which generates the
//! values to be written to the color attachment. Various testing and discarding operations can
//! be performed both before and after the fragment shader ("early" and "late" fragment tests),
//! including:
//! - Discard rectangle test
//! - Scissor test
//! - Sample mask test
//! - Depth bounds test
//! - Stencil test
//! - Depth test
//! 8. Color attachment output: the final pixel data is written to a framebuffer. Blending and
//! logical operations can be applied to combine incoming pixel data with data already present
//! in the framebuffer.
//!
//! A graphics pipeline contains many configuration options, which are grouped into collections of
//! "state". Often, these directly correspond to one or more steps in the graphics pipeline. Each
//! state collection has a dedicated submodule.
//!
//! Once a graphics pipeline has been created, you can execute it by first *binding* it in a command
//! buffer, binding the necessary vertex buffers, binding any descriptor sets, setting push
//! constants, and setting any dynamic state that the pipeline may need. Then you issue a `draw`
//! command.

//! Configures how data from vertex buffers is read into vertex shader input locations.
//!
//! The vertex input stage is the stage where data is read from a buffer and fed into the vertex
//! shader. After each invocation of the vertex shader, the pipeline then proceeds to the input
//! assembly stage.
//!
//! # Input locations and components
//!
//! Input data is assigned per shader input location. Locations are set by adding the `location`
//! layout qualifier to an input variable in GLSL. A single location contains four data elements,
//! named "components", which are each 32 bits in size. These correspond to the `x`, `y`, `z` and
//! `w` (or equivalently `r`, `g`, `b`, `a`) components of a `vec4` inside the shader.
//! A component can contain at most one value, and data types that are smaller than 32 bits will
//! still take up a whole component, so a single `i8vec4` variable will still take up all four
//! components in a location, even if not all bits are actually used.
//!
//! A variable may take up fewer than four components. For example, a single `float` takes up only
//! one component, a `vec2` takes up two, and so on. Using the `component` layout qualifier in GLSL,
//! it is possible to fit multiple variables into a single four-component location slot, as long
//! as the components of each variable don't overlap.
//!
//! If the input variable is an array, then it takes up a series of consecutive locations. Each
//! element of the array always starts at a new location, regardless of whether there is still room
//! in the previous one. So, for example, an array of three `vec2` takes three locations, since
//! `vec2` alone needs one location. An array can be decorated with the `component` qualifier as
//! well; this is equivalent to applying the qualifier to every element of the array. If elements do
//! not use all components in their locations, those free components can be filled with additional
//! variables, just like for non-array types.
//!
//! Matrices are laid out as if they were an array of column vectors. Thus, a `mat4x3` is laid out
//! as an array of four `vec3`s, `mat2x4` as two `vec4`s. As with individual vectors, each column of
//! the matrix uses up as many components of its location as there are rows in the matrix, and the
//! remaining components are available for additional variables as described above. However, it is
//! not possible to use the `component` qualifier on a matrix.
//!
//! If a 64-bit value is to be passed to a shader, it will take up two adjacent components. Vectors
//! of 64-bit values are correspondingly twice as large: `dvec2` takes up all four components of a
//! location, `dvec4` takes two full locations, while `dvec3` takes one full location and the first
//! two components of the next. An array or matrix of a 64-bit type is made up of multiple adjacent
//! 64-bit elements, just like for smaller types: each new element starts at a fresh location.
//!
//! # Input attributes
//!
//! An input attribute is a mapping between data in a vertex buffer and the locations and components
//! of the vertex shader.
//!
//! Input attributes are assigned on a per-location basis; it is not possible to assign attributes
//! to individual components. Instead, each attribute specifies up to four values to be read from
//! the vertex buffer at once, which are then mapped to the four components of the given location.
//! Like the texels in an image, each attribute's data format in a vertex buffer is described by a
//! [`Format`]. The input data doesn't have to be an actual color, the format simply describes the
//! type, size and layout of the data for the four input components. For example,
//! `Format::R32G32B32A32_SFLOAT` will read four `f32` values from the vertex buffer and assigns
//! them to the four components of the attribute's location.
//!
//! It is possible to specify a `Format` that contains less than four components. In this case, the
//! missing components are given default values: the first three components default to 0, while the
//! fourth defaults to 1. This means that you can, for example, store only the `x`, `y` and `z`
//! components of a vertex position in a vertex buffer, and have the vertex input state
//! automatically set the `w` value to 1 for you. An exception to this are 64-bit values: these do
//! *not* receive default values, meaning that components that are missing from the format are
//! assigned no value and must not be used in the shader at all.
//!
//! When matching attribute formats to shader input types, the following rules apply:
//! - Signed integers in the shader must have an attribute format with a `SINT` type.
//! - Unsigned integers in the shader must have an attribute format with a `UINT` type.
//! - Floating point values in the shader must have an attribute format with a type other than
//! `SINT` or `UINT`. This includes `SFLOAT`, `UFLOAT` and `SRGB`, but also `SNORM`, `UNORM`,
//! `SSCALED` and `USCALED`.
//! - 64-bit values in the shader must have a 64-bit attribute format.
//! - 32-bit and smaller values in the shader must have a 32-bit or smaller attribute format, but
//! the exact number of bits doesn't matter. For example, `Format::R8G8B8A8_UNORM` can be used
//! with a `vec4` in the shader.
//!
//! # Input bindings
//!
//! An input binding is a definition of a Vulkan buffer that contains the actual data from which
//! each input attribute is to be read. The buffer itself is referred to as a "vertex buffer", and
//! is set during drawing with the
//! [`bind_vertex_buffers`](crate::command_buffer::AutoCommandBufferBuilder::bind_vertex_buffers)
//! command.
//!
//! The data in a vertex buffer is typically arranged into an array, where each array element
//! contains the data for a single vertex shader invocation. When deciding which element read from
//! the vertex buffer for a given vertex and instance number, each binding has an "input rate".
//! If the input rate is `Vertex`, then the vertex input state advances to the next element of that
//! buffer each time a new vertex number is processed. Likewise, if the input rate is `Instance`,
//! it advances to the next element for each new instance number. Different bindings can have
//! different input rates, and it's also possible to have multiple bindings with the same input
//! rate.

//! A pipeline layout describes the layout of descriptors and push constants used by a pipeline.
//!
//! # Overview
//!
//! The layout itself only *describes* the descriptors and push constants, and does not contain
//! their content itself. Instead, you can think of it as a `struct` definition that states which
//! members there are, what types they have, and in what order.
//! One could imagine a Rust definition somewhat like this:
//!
//! ```text
//! #[repr(C)]
//! struct MyPipelineLayout {
//! push_constants: Pc,
//! descriptor_set0: Ds0,
//! descriptor_set1: Ds1,
//! descriptor_set2: Ds2,
//! descriptor_set3: Ds3,
//! }
//! ```
//!
//! Of course, a pipeline layout is created at runtime, unlike a Rust type.
//!
//! # Layout compatibility
//!
//! When binding descriptor sets or setting push constants, you must provide a pipeline layout.
//! This pipeline is used to decide where in memory Vulkan should write the new data. The
//! descriptor sets and push constants can later be read by dispatch or draw calls, but only if
//! the bound pipeline being used for the command has a layout that is *compatible* with the layout
//! that was used to bind the resources.
//!
//! *Compatible* means that the pipeline layout must be the same object, or a different layout in
//! which the push constant ranges and descriptor set layouts were be identically defined.
//! However, Vulkan allows for partial compatibility as well. In the `struct` analogy used above,
//! one could imagine that using a different definition would leave some members with the same
//! offset and size within the struct as in the old definition, while others are no longer
//! positioned correctly. For example, if a new, incompatible type were used for `Ds1`, then the
//! `descriptor_set1`, `descriptor_set2` and `descriptor_set3` members would no longer be correct,
//! but `descriptor_set0` and `push_constants` would remain accessible in the new layout.
//! Because of this behaviour, the following rules apply to compatibility between the layouts used
//! in subsequent descriptor set binding calls:
//!
//! - An incompatible definition of `Pc` invalidates all bound descriptor sets.
//! - An incompatible definition of `DsN` invalidates all bound descriptor sets *N* and higher.
//! - If *N* is the highest set being assigned in a bind command, and it and all lower sets
//! have compatible definitions, including the push constants, then descriptor sets above *N*
//! remain valid.
//!
//! [`SyncCommandBufferBuilder`](crate::command_buffer::synced::SyncCommandBufferBuilder) keeps
//! track of this state and will automatically remove descriptor sets that have been invalidated
//! by incompatible layouts in subsequent binding commands.
//!
//! # Creating pipeline layouts
//!
//! A pipeline layout is a Vulkan object type, represented in Vulkano with the `PipelineLayout`
//! type. Each pipeline that you create holds a pipeline layout object.
//!
//! By default, creating a pipeline automatically builds a new pipeline layout object describing the
//! union of all the descriptors and push constants of all the shaders used by the pipeline.
//! However, it is also possible to create a pipeline layout separately, and provide that to the
//! pipeline constructor. This can in some cases be more efficient than using the auto-generated
//! pipeline layouts.

//! the CPU). Consequently it is a CPU-intensive operation that should be performed at
//! initialization or during a loading screen.
//!
//! There are two kinds of pipelines:
//!
//! - `ComputePipeline`s, for compute operations (general-purpose operations that read/write data
//! in buffers or raw pixels in images).
//! - `GraphicsPipeline`s, for graphical operations (operations that take vertices as input and
//! write pixels to a framebuffer).
//!
//! # Creating a compute pipeline.
//!
//! In order to create a compute pipeline, you first need a *shader entry point*.
//!
//! TODO: write the rest
//! For now vulkano has no "clean" way to create shaders ; everything's a bit hacky
//!
//! # Creating a graphics pipeline
//!
//! A graphics operation takes vertices or vertices and indices as input, and writes pixels to a
//! framebuffer. It consists of multiple steps:
//!
//! - A *shader* named the *vertex shader* is run once for each vertex of the input.
//! - Vertices are assembled into primitives.
//! - Optionally, a shader named the *tessellation control shader* is run once for each primitive
//! and indicates the tessellation level to apply for this primitive.
//! - Optionally, a shader named the *tessellation evaluation shader* is run once for each vertex,
//! including the ones newly created by the tessellation.
//! - Optionally, a shader named the *geometry shader* is run once for each line or triangle.
//! - The vertex coordinates (as outputted by the geometry shader, or by the tessellation
//! evaluation shader if there's no geometry shader, or by the vertex shader if there's no
//! geometry shader nor tessellation evaluation shader) are turned into screen-space coordinates.
//! - The list of pixels that cover each triangle are determined.
//! - A shader named the fragment shader is run once for each pixel that covers one of the
//! triangles.
//! - The depth test and/or the stencil test are performed.
//! - The output of the fragment shader is written to the framebuffer attachments, possibly by
//! mixing it with the existing values.
//!
//! All the sub-modules of this module (with the exception of `cache`) correspond to the various
//! stages of graphical pipelines.
//!
//! > **Note**: With the exception of the addition of the tessellation shaders and the geometry
//! > shader, these steps haven't changed in the past decade. If you are familiar with shaders in
//! > OpenGL 2 for example, don't worry as it works in the same in Vulkan.
//!
//! > **Note**: All the stages that consist in executing a shader are performed by a microprocessor
//! > (unless you happen to use a software implementation of Vulkan). As for the other stages,
//! > some hardware (usually desktop graphics cards) have dedicated chips that will execute them
//! > while some other hardware (usually mobile) perform them with the microprocessor as well. In
//! > the latter situation, the implementation will usually glue these steps to your shaders.
//!
//! Creating a graphics pipeline follows the same principle as a compute pipeline, except that
//! you must pass multiple shaders alongside with configuration for the other steps.
//!
//! TODO: add an example
// TODO: graphics pipeline params are deprecated, but are still the primary implementation in order

//! # Vertex sources definition
//!
//! When you create a graphics pipeline object, you need to pass an object which indicates the
//! layout of the vertex buffer(s) that will serve as input for the vertex shader. This is done
//! by passing an implementation of the `VertexDefinition` trait.
//!
//! In addition to this, the object that you pass when you create the graphics pipeline must also
//! implement the `VertexSource` trait. This trait has a template parameter which corresponds to the
//! list of vertex buffers.
//!
//! The vulkano library provides some structs that already implement these traits.
//! The most common situation is a single vertex buffer and no instancing, in which case you can
//! pass a `SingleBufferDefinition` when you create the pipeline.
//!
//! # Implementing `Vertex`
//!
//! The implementations of the `VertexDefinition` trait that are provided by vulkano (like
//! `SingleBufferDefinition`) require you to use a buffer whose content is `[V]` where `V`
//! implements the `Vertex` trait.
//!
//! The `Vertex` trait is unsafe, but can be implemented on a struct with the `impl_vertex!`
//! macro.
//!
//! # Example
//!
//! ```ignore // TODO:
//! # #[macro_use] extern crate vulkano
//! # fn main() {
//! # use std::sync::Arc;
//! # use vulkano::device::Device;
//! # use vulkano::device::Queue;

//! use vulkano::memory::HostVisible;
//! use vulkano::pipeline::vertex::;
//! # let device: Arc<Device> = return;
//! # let queue: Arc<Queue> = return;
//!
//! struct Vertex {
//! position: [f32; 2]
//! }
//!
//! impl_vertex!(Vertex, position);
//!
//! let usage = BufferUsage {
//! vertex_buffer: true,
//! .. BufferUsage::none()
//! };
//!
//! let vertex_buffer = BufferAccess::<[Vertex], _>::array(&device, 128, &usage, HostVisible, &queue)
//! .expect("failed to create buffer");
