Detailed Description
Complete declarative description of a generated compute shader.
Pure value type. Consumed by ShaderFoundry::load_shader(const ShaderSpec&) which emits SPIR-V assembly via VKShaderModule::emit_spirv_asm() and assembles it via VKShaderModule::create_from_spirv_asm(). No shaderc or GLSL toolchain is involved.
The op field selects a named operation the emitter knows how to lower to SPIR-V opcodes deterministically. PC fields are consumed in declaration order as operands.
auto spec = ShaderSpec::Assemble{}
.pc("gain")
.pc("offset")
.build();
Assemble & op(KernelOp o)
Set the named operation the emitter will lower to SPIR-V.
Definition ShaderSpec.hpp:360
Assemble & pc(std::string name, Kakshya::GpuDataFormat format)
Declare a push constant field with explicit format.

Assemble & ssbo(std::string name, BindingDirection direction, Kakshya::GpuDataFormat format, Kakshya::DataModality modality=Kakshya::DataModality::SCALAR_F32)
Declare an SSBO binding.
