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
This is an older version of Boost and was released in 2023. The current version is 1.89.0.
Callable Object types that work with ResultOf utility to determine the result of a call.
note Once C++ supports the decltype keyword, all models
of Callable Object
will also be models of Deferred
Callable Object, because function objects won't need client-side
support for result_of.
Notation
