The project strusBase implements some libraries with common functions and interfaces of the strus projects. The project strus provides some libraries for building a search engine for information retrieval. The project is hosted at github.

The most important interface provided by strusBase is the error buffer interface. This interface provides a mechnism to buffer exceptions thrown by strus functions. C++ exceptions cannot be thrown accross interface boundaries because C++ does not allow exceptions be caught thrown by another shared object (module) or library without intrusive build and linkage rules (all binary artefacts built with the same compiler and version and with all symbols exported). [See C++ Coding Standards: 101 Rules, Guidelines, and Best Practices By Herb Sutter, Andrei Alexandrescu: 61. Don’t allow exceptions to propagate across module boundaries]
