FGuardedInt32

using FGuardedInt32 = TGuardedInt<int32>

Guarded 32-bit integer class. Used to deal with integer data from untrusted sources in size computations etc.

FGuardedInt64

using FGuardedInt64 = TGuardedInt<int64>

Guarded 64-bit integer class. Used to deal with integer data from untrusted sources in size computations etc.

TGuardedSignedInt

template<typename SignedType >

using TGuardedSignedInt = TGuardedInt<SignedType>

Legacy alias for the previously signed-integer-only implementation.
