kernelsOf function

Map<String, ComputeKernel> kernelsOf(ShaderBundle bundle)

The kernels bundle's kernel section carries, read and checked, by stage name; empty when it has none. What a device's loadShaders calls.

Throws ShaderBundleException naming the bundle for a section that is not the payload, and for a kernel whose source does not read, with the reason.

Implementation

Map<String, ComputeKernel> kernelsOf(ShaderBundle bundle) {
  final sources = decodeKernelSection(bundle);
  final kernels = <String, ComputeKernel>{};
  for (final MapEntry(key: name, value: source) in sources.entries) {
    try {
      kernels[name] = ComputeKernel.parse(source, name: name);
    } on ComputeKernelException catch (error) {
      throw ShaderBundleException(
        name: bundle.name,
        reason: 'its kernel "$name" does not read: ${error.message}',
      );
    }
  }
  return kernels;
