Detailed Description

Parsed representation of a stringified field lambda.

Produced by MF_FIELD, which stringifies the lambda text at the call site. Shares an input shape with Portal::Graphics::KernelSource but not a consumer, and differs in one respect: the parameter list is retained verbatim rather than stripped to identifiers, because a field is emitted as a standalone GLSL function above main() where the signature needs types. KernelSource strips them because a main-injected body receives its operands as file-scope declarations.

Nothing here knows about ShaderSpec. The four members map onto the four arguments of ShaderSpec::Assemble::function(), and that call happens at the site assembling a spec, which is above both Kinesis and Portal.

auto spec = ShaderSpec::Assemble{}
    .ssbo("pos", BindingDirection::InOut, Kakshya::GpuDataFormat::VEC4_F32)
    .function(swirl.source.return_type, swirl.source.name,
              swirl.source.params, swirl.source.body)
    .kernel(MF_KERNEL(...))
    .build();
