problem static method

String? problem(String stage, { required int textures, required int samplers, required int uniformBlocks, })

Why a stage named stage that binds textures textures, samplers samplers and uniformBlocks uniform blocks is over the budget, or null when it is within it.

Implementation

static String? problem(
  String stage, {
  required int textures,
  required int samplers,
  required int uniformBlocks,
}) {
  String over(int count, int budget, String what) =>
      'the stage "$stage" binds $count $what, and a stage may bind at most '
      '$budget on WebGPU, the engine\'s own bindings included: that is '
      'what every WebGPU device guarantees. Bind fewer in the material, '
      'or pack two maps into the channels of one';
  if (textures > MaterialStageBudget.textures) {
    return over(textures, MaterialStageBudget.textures, 'textures');
  }
  if (samplers > MaterialStageBudget.samplers) {
    return over(samplers, MaterialStageBudget.samplers, 'samplers');
  }
  if (uniformBlocks > MaterialStageBudget.uniformBlocks) {
    return over(
      uniformBlocks,
      MaterialStageBudget.uniformBlocks,
      'uniform blocks',
    );
  }
  return null;
