Module rendy_core::hal::pso

Raw Pipeline State Objects

This module contains items used to create and manage Pipelines.

Structs

AttributeDesc	Vertex attribute description. Notably, completely separate from resource Descriptors used in DescriptorSets.
BakedStates	Baked-in pipeline states.
BlendDesc	A description of an equation for how to blend transparent, overlapping fragments.
BlendState	Specifies whether to use blending, and if so, which operations to use for color and alpha channels.
ClearRect	A simple struct describing a rect with integer coordinates.
ColorBlendDesc	PSO color target descriptor.
ColorMask	Target output color mask.
ComputePipelineDesc	A description of the data needed to construct a compute pipeline.
DepthBias	A depth bias allows changing the produced depth values for fragments slightly but consistently. This permits drawing of multiple polygons in the same plane without Z-fighting, such as when trying to draw shadows on a wall.
DepthStencilDesc	PSO depth-stencil target descriptor.
DepthTest	Depth test state.
DescriptorPoolCreateFlags	Descriptor pool creation flags.
DescriptorRangeDesc	Set of descriptors of a specific type.
DescriptorSetCopy	Copies a range of descriptors to be bound from one descriptor set to another Should be provided to the copy_descriptor_sets method of a Device.
DescriptorSetLayoutBinding	Information about the contents of and in which stages descriptors may be bound to a descriptor set at a certain binding point. Multiple DescriptorSetLayoutBindings are assembled into a DescriptorSetLayout, which is then allocated into a DescriptorSet using a DescriptorPool.
DescriptorSetWrite	Writes the actual descriptors to be bound into a descriptor set. Should be provided to the write_descriptor_sets method of a Device.
Element	A struct element descriptor.
EntryPoint	Shader entry point.
Face	Face.
GraphicsPipelineDesc	A description of all the settings that can be altered when creating a graphics pipeline.
GraphicsShaderSet	A complete set of shaders to build a graphics pipeline.
InputAssemblerDesc	All the information needed to create an input assembler.
Multisampling
PipelineCreationFlags	Pipeline creation flags.
PipelineStage	Stages of the logical pipeline.
Rasterizer	Rasterization state.
Rect	A simple struct describing a rect with integer coordinates.
ShaderStageFlags	Combination of different shader pipeline stages.
Sided	A generic struct holding the properties of two sides of a polygon.
Specialization	Specialization information structure.
SpecializationConstant	Specialization constant for pipelines.
StencilFace	Complete stencil state for a given side of a face.
StencilTest	Defines a stencil test. Stencil testing is an operation performed to cull fragments; the new fragment is tested against the value held in the stencil buffer, and if the test fails the fragment is discarded.
VertexBufferDesc	Vertex buffer description. Notably, completely separate from resource Descriptors used in DescriptorSets.
Viewport	A viewport, generally equating to a window on a display.

Enums

AllocationError	An error allocating descriptor sets from a pool.
BasePipeline	A reference to a parent pipeline. The assumption is that a parent and derivative/child pipeline have most settings in common, and one may be switched for another more quickly than entirely unrelated pipelines would be.
BlendOp	Blending operations.
Comparison	A pixel-wise comparison function.
CreationError	Error types happening upon PSO creation on the device side.
Descriptor	A handle to a specific shader resource that can be bound for use in a DescriptorSet. Usually provided in a DescriptorSetWrite
DescriptorType	DOC TODO: Grasping and remembering the differences between these types is a tough task. We might be able to come up with better names? Or even use tuples to describe functionality instead of coming up with fancy names.
Factor	Defines the possible blending factors. During blending, the source or destination fragment may be multiplied by a factor to produce the final result.
FrontFace	The front face winding order of a set of vertices. This is the order of vertexes that define which side of a face is the "front".
LogicOp	Logic operations used for specifying blend equations.
PolygonMode	Methods for rasterizing polygons, ie, turning the mesh into a raster image.
Primitive	Describes the type of geometric primitives, created from vertex data.
Stage	Which program stage this shader represents.
State	Pipeline state which may be static or dynamic.
StencilOp	The operation to use for stencil masking.
VertexInputRate	The rate at which to advance input data to shaders for the given buffer

Traits

DescriptorPool

A descriptor pool is a collection of memory from which descriptor sets are allocated.

Functions

Safely read SPIR-V
