```suggestion

  uint32_t RootParametersOffset;
  uint32_t NumStaticSamplers;
  uint32_t StaticSamplersOffset;

  uint32_t getEncodedFlags();
#include "llvm/BinaryFormat/DXContainerConstants.def"
```

IMO this makes it a bit clearer what's going on and less likely to be confused that there's a `getEncodedFlags` member variable.

(also, github has messed up the diff of this suggestion and I don't know how to fix it)
