We will be using the RxCpp library to write our reactive programs for rest of the book. The RxCpp library is a header-only C++ library that can be downloaded from a GitHub repo: http://reactive-extensions.github.io/RxCpp/. The RxCpp library relies on Modern C++ constructs, such as language-level concurrency, lambda functions/expressions, functional composition/transformation, and operator-overloading, to implement reactive programming constructs. The RxCpp library is structured along the lines of libraries such as Rx.net and Rxjava. Like any other reactive programming framework, there are some key constructs that everyone should understand before they write the first line of code. They are:
- Observables (Observable Streams)
- Observers (who subscribe to the Observables)
- Operators (for example, filters, transformations, and reductions)
- Schedulers...
