// This file contains byte swapping routines for use in safe_browsing::dmg. The
// pattern is to use type-based overloading of the form ConvertBigEndian(T*) to
// swap all structures from big-endian to host-endian. This file provides the
// implementations for scalars, which are inlined since the OSSwap functions
// themselves are macros that call compiler intrinsics.
