Detailed Description

Parsed representation of a user-supplied kernel lambda.

Produced by the MF_KERNEL macro, which stringifies the lambda text at the call site. The parameter names must match binding and push constant field names declared on the enclosing ShaderSpec in declaration order: SSBO bindings first, then PC fields, then optionally a uint32_t index parameter named i.

The body is extracted verbatim between the outermost braces and injected into the generated GLSL compute shader by the emitter.

auto spec = ShaderSpec::Assemble{}
    .ssbo("sig", BindingDirection::InOut, Kakshya::GpuDataFormat::FLOAT32)
    .pc("gain")
    .kernel(MF_KERNEL([](float* sig, float gain, uint32_t i) {
        sig[i] = sig[i] * gain + sin(float(i) * 0.01f);
    }))
    .build();
