+.. class:: string_view
+This is an internal implementation of `std::string_view
+<>`__. This was done 
+:code:`std::string_view` is part of the C++17 standard and therefore cannot be 
assumed in our
+supported compilers (which are currently only C++11).
+:class:`string_view` provides a read only view into memory allocated elsewhere 
and is handy for when
+passing around pieces of memory, such as pieces of an HTTP header. It is 
essentially a pointer and a
+length and a quick glance at our internal API will provide numerous places 
this kind of data is
+This implementation is intended to be as similar as possible to the standard 
version to avoid
+transition difficulties if / when we upgrade to C++17. For this reason no 
additional features,
+regardless of how useful we might find them, have been or will be added to 
this class.
+The only known difference at this time is the literal operator is 
:code:`""_sv` instead of
+:code:`""sv` as it is for :code:`std::string_view`. The reason is a compiler 
limitation which does
+not allow non-compiler headers to define literal operators without a leading 
``_``. The use would be
+.. code-block:: cpp
+   ts::string_view ts_v = "A literal string"_sv; // ts::string_view
+   std::string_view std_v = "A literal string"sv; // std::string_view
+If you discover any other differences, that is a bug in our implementation and 
should be fixed.
+For a class that provides a much richer set of text manipulation methods, see 
+which is a subclass of :class:`string_view`.
+There is no shortage of additional reference material available, beyond the 
basic description noted
+above, which serves to describe the API and usage of this class, and 
duplicating it here would serve
+no purpose.
