+/** The type of string_view used by the library
+
+    String views are used to pass character
+    buffers into or out of functions. Ownership
+    of the underlying character buffer is not
+    transferred; the caller is responsible for
+    ensuring that the lifetime of character
+    buffer extends until it is no longer
+    referenced.
+
+    @note This alias is no longer supported and
+    should not be used in new code. Please use
+    `core::string_view` instead.
+
+    This alias is included for backwards
+    compatibility with earlier versions of the
+    library.
+
+    However, it will be removed in future releases,
+    and using it in new code is not recommended.
+
+    Please use the updated version instead to
+    ensure compatibility with future versions of
+    the library.
