+[section Tuning classes for fast lexical conversions]
+Because of `boost::lexical_cast` optimizations for `boost::iterator_range<character_type*>`, it is possibile to make very fast lexical conversions for non zero terminated strings, substrings and user-defined classes.
+
+Consider the following example:
+``
+ class example_class {
+ char non_zero_terminated_data[10];
+ std::size_t data_length;
+
+ public:
+ example_class();
+ void fill_data();
+
+ const char* data() const {
+ return non_zero_terminated_data;
+ }
+
+ std::size_t size() const {
+ return data_length;
+ }
+ };
+
+ inline std::ostream& operator << (std::ostream& ostr, const example_class& rhs) {
+ return ostr << boost::make_iterator_range(rhs.data(), rhs.data() + rhs.size());
+ }
+``
+
+This is a good generic solution for most use cases.
+But we can make it even faster for some performance critical applications. During conversion, we loose speed at:
+
+* `std::ostream` construction (it makes some heap allocations)
+* `operator <<` (it copyies one by one all the symbols to an instance of `std::ostream`)
+* `std::ostream` destruction (it makes some heap deallocations)
+
+We can avoid all of this, by specifieng an overload for `boost::lexical_cast`:
+``
+namespace boost {
+ template <class OutT>
+ OutT lexical_cast(const example_class& rhs) {
+ return boost::lexical_cast<OutT>(
+ boost::make_iterator_range(rhs.data(), rhs.data() + rhs.size())
+ );
+ }
+}
+``
+Now `boost::lexical_cast<some_type>(example_class_instance)` conversions won't copy data and construct heavy STL stream objects. See [link boost_lexical_cast.performance Performance] section for info on `boost::iterator_range` conversion performance.

+* [*Question:] What is the fastest way to convert a non zero terminated string or a substring using `boost::lexical_cast`?
+ * [*Answer:] Use `boost::iterator_range` for conversion. For example, if you whant to convert to `int` two characters from a string `str`, you shall write `lexacal_cast<int>(make_iterator_range(str.c_str(), str.c_str() + 2));`.
