Crate naga[−][src]

Universal shader translator.

The central structure of the crate is Module.

To improve performance and reduce memory usage, most structures are stored in an Arena, and can be retrieved using the corresponding Handle.

Modules

back	Functions which export shader modules into binary and text formats.
front	Parsers which load shaders into memory.
proc	Module processing functionality.

Arena	An arena holding some kind of component (e.g., type, constant, instruction, etc.) that can be referenced.
Constant	Constant value.
EarlyDepthTest	Early fragment tests. In a standard situation if a driver determines that it is possible to switch on early depth test it will. Typical situations when early depth test is switched off:
EntryPoint	Exported function, to be run at a certain stage in the pipeline.
Function	A function defined in the module.
FunctionArgument	A function argument.
GlobalUse	Indicates how a global variable is used.
GlobalVariable	Variable defined at module level.
Handle	A strongly typed reference to a SPIR-V element.
Header	Metadata for a given module.
LocalVariable	Variable defined at function level.
Module	Shader module.
StorageAccess	Flags describing an image.
StructMember	Member of a user-defined structure.
SwitchCase	A case for a switch statement.
Type	A data type declared in the module.

ArraySize	Size of an array.
BinaryOperator	Operation that can be applied on two values.
Binding	Describes how an input/output variable is to be bound.
BuiltIn	Built-in inputs and outputs.
ConservativeDepth	Enables adjusting depth without disabling early Z.
ConstantInner	Additional information, dependendent on the kind of constant.
DerivativeAxis	Axis on which to compute a derivative.
Expression	An expression that can be evaluated to obtain a value.
ImageClass	Sub-class of the image type.
ImageDimension	The number of dimensions an image has.
Interpolation	The interpolation qualifier of a binding or struct field.
MathFunction	Built-in shader function for math.
RelationalFunction	Built-in shader function for testing relation between values.
SampleLevel	Sampling modifier to control the level of detail.
ScalarKind	Primitive type for a scalar.
ScalarValue	A literal scalar value, used in constants.
ShaderStage	Stage of the programmable pipeline.
Statement	Instructions which make up an executable block.
StorageClass	Class of storage for variables.
StorageFormat
TypeInner	Enum with additional information, depending on the kind of type.
UnaryOperator	Operation that can be applied on a single value.
VectorSize	Number of components in a vector.

Block	A code block is just a vector of statements.
Bytes	Number of bytes.
FastHashMap	Hash map that is faster but not resilient to DoS attacks.
FastHashSet	Hash set that is faster but not resilient to DoS attacks.
