checkStorageBinding function

int checkStorageBinding(StorageBuffer buffer, DeviceLimits limits, { int offsetInBytes = 0, int? sizeInBytes, })

Checks a storage binding of buffer from offsetInBytes, sizeInBytes long (to the end when null), against limits: the range lies inside the buffer and starts at a multiple of DeviceLimits.minStorageBufferOffsetAlignment. Answers the size bound.

Throws a RangeError naming the call that is wrong.

Implementation

int checkStorageBinding(
  StorageBuffer buffer,
  DeviceLimits limits, {
  int offsetInBytes = 0,
  int? sizeInBytes,
}) {
  final size = sizeInBytes ?? buffer.lengthInBytes - offsetInBytes;
  if (offsetInBytes < 0 ||
      size < 0 ||
      offsetInBytes + size > buffer.lengthInBytes) {
    throw RangeError(
      'bindStorageBuffer: $size bytes from $offsetInBytes leave a buffer of '
      '${buffer.lengthInBytes}',
    );
  }
  final alignment = limits.minStorageBufferOffsetAlignment;
  if (alignment > 0 && offsetInBytes % alignment != 0) {
    throw RangeError(
      'bindStorageBuffer: offset $offsetInBytes is not a multiple of '
      'minStorageBufferOffsetAlignment ($alignment) on this device',
    );
  }
  return size;
}
