The documentation promises the following will work:
std::bitset<32> foo = std::bitset<32>(12345678); channel << IOFormatMemSep::all << foo << IOCtrl::endl; /* OUTPUT: 4e 61 bc 00 */
This feature is missing from Channel 2.0. It either needs to be implemented in the code (preferred) or dropped from the docs.
My initial thought on implementing this is adding the following to Channel:
template<size_t S> Channel& operator<<(const std::bitset<S>& rhs) { if (!can_parse()) { return *this; } // Bitsets should always be rendered via memory auto prior_mem_view = this->fmt.ptr(); this->fmt << IOFormatPtr::memory; inject(stringify(&rhs, this->fmt)); // Restore prior memory view. this->fmt << prior_mem_view; return *this; }
