-// Support for logging binary data as hex
-// format flags, any combination of the following:
-// {:X} - print in uppercase.
-// {:s} - don't separate each byte with space.
-// {:p} - don't print the position on each line start.
-// {:n} - don't split the output to lines.
-// {:a} - show ASCII if :n is not set
-
-//
-// Examples:
-//
-// std::vector<char> v(200, 0x0b);
-// logger->info("Some buffer {}", spdlog::to_hex(v));
-// char buf[128];
-// logger->info("Some buffer {:X}", spdlog::to_hex(std::begin(buf), std::end(buf)));
