Boost
C++ Libraries
...one of the most highly
regarded and expertly designed C++ library projects in the
world.
— Herb Sutter and Andrei
Alexandrescu, C++
Coding Standards
Three types of objects are currently supported by the library:
std::pair<iterator,iterator>
Even though the behavior of the primary templates are exactly such that standard
containers will be supported by default, the requirements are much lower
than the standard container requirements. For example, the utility class
iterator_range
implements the minimal interface
required to make the class a Forward
Range.
Please also see Range concepts for more details.
