Termbench is a project to benchmark the terminal emulators backend bandwidth throughput.

Therefore not just a CLI executable (tb) will be provided but also a library that one can link against to test against your own terminal emulator backend without being affected by your rendering pipeline.

The library is written in modern C++17 with a strong focus on clean, readable, and maintainable code so that other project might possibly also be able to benefit from this library, if not even integrating it.

Adding a C-API binding is considered as soon there is also interest from other projects that cannot use the C++ API.
