load static method

Future<PipelineSet> load(GpuDevice device, String bundle, Iterable<PipelineSpec> specs)

Loads bundle on device and creates a pipeline for each of specs. Throws a StateError naming any shader the bundle lacks.

Implementation

static Future<PipelineSet> load(
  GpuDevice device,
  String bundle,
  Iterable<PipelineSpec> specs,
) async {
  final library = await device.loadShaderLibrary(bundle);
  final pipelines = <PipelineSpec, GpuPipeline>{};
  for (final spec in specs) {
    final vertex = library[spec.vertex];
    final fragment = library[spec.fragment];
    if (vertex == null || fragment == null) {
      throw StateError(
        '$bundle has no ${vertex == null ? spec.vertex : spec.fragment}.',
      );
    }
    pipelines[spec] = device.pipeline(vertex, fragment, layout: spec.layout);
  }
  return PipelineSet._(pipelines);
