#include <tpm2_util.h>

Static Public Member Functions
static constexpr AttributeWrapperT	read (UnderlyingT attributes)
static constexpr UnderlyingT	render (AttributeWrapperT attributes)

Detailed Description

template<std::unsigned_integral UnderlyingT, typename AttributeWrapperT, PropMap< bool AttributeWrapperT::*, UnderlyingT >... props>
class Botan::TPM2::AttributeWrapper< UnderlyingT, AttributeWrapperT, props >

This is an internal helper structure to wrap TPMA_* attribute bit fields.

Template Parameters

UnderlyingT	the TPMA_* bit field type
AttributeWrapperT	the C++ struct type that wraps the TPMA_* bit field
props	a bunch of std::pair mappping boolean members of AttributeWrapperT to the bit masks of the TPMA_* type
