Span
A Span is an object that can refer to a contiguous sequence of objects.
Definition span.h:98

HexStr
std::string HexStr(const Span< const uint8_t > s)
Convert a span of bytes to a lower-case hexadecimal string.
Definition hex_base.cpp:29

HexDigit
signed char HexDigit(char c)
Definition hex_base.cpp:63

span.h

MakeUCharSpan
constexpr auto MakeUCharSpan(V &&v) -> decltype(UCharSpanCast(Span{std::forward< V >(v)}))
Like the Span constructor, but for (const) unsigned char member types only.
