Append to this string the optionally specified numChars characters starting at the specified position in the bsl::string_view object, obtained from the specified suffix, or its tail starting at position if numChars exceeds the length of this tail. If numChars is not specified, npos is used. Return a reference providing modifiable access to this string. Throw out_of_range if position > strView.length(). Throw length_error if the length of the resulting string exceeds max_size().
