config_from_spec()

GpuComputeConfig MayaFlux::Yantra::config_from_spec ( const Portal::Graphics::ShaderSpec &  spec )

inline

Derive a GpuComputeConfig from a ShaderSpec.

Compiles (or retrieves cached) the shader via ShaderFoundry and packages the result with workgroup size and push constant size. Returns a config with INVALID_SHADER on compilation failure.

Callers use this alongside bindings_from_spec() to configure any concrete GpuExecutionContext subclass without depending on a specific executor type.

auto spec  = ShaderSpec::Assemble{}
    .ssbo("sig", BindingDirection::InOut, Kakshya::GpuDataFormat::FLOAT32)
    .pc("gain")
    .op(KernelOp::Scale)
    .build();
 
auto cfg      = config_from_spec(spec);
auto bindings = bindings_from_spec(spec);
 
auto exec = std::make_shared<ShaderExecutionContext<>>(cfg, bindings);
my_op->set_gpu_backend(exec);
