The Resource Loan pattern

The Loan pattern, as the  name suggest, loans a resource to a function  In the example given below, a file handle is loaned to consumers of the class. It performs following steps:

1. It creates a resource that you can use (a file handle )
2. It loans the resource (file handle ) to functions  (lambdas) that will use it
3. This function is passed by the caller and executed by the resource holder
4. The resource (file handle ) is closed or destroyed  by the resource holder

The following code implements the Resource Loan pattern for resource management. The pattern helps to avoid resource leakage when writing code:

//----------- ResourceLoan.cpp #include <rxcpp/rx.hpp> using namespace std; ////////////////////////// // implementation ...
