Python-Rust-benchmark VS Warframe-OCR

I got 3000x speed-up too!

Yes, you can link them statically. Here's a Python script I wrote to install and build a Python module in Rust. It will install the required development libraries on Linux and build a static build of tesseract on Windows (it also downloads the LLVM based clang compiler, I forgot why). Then it set up two environment variables VCPKG_ROOT to discover the tesseract library and RUSTFLAGS -Ctarget-feature=+crt-static (this forces the vpkg crate to link tesseract:x64-windows-static and not the dynamic version).

Tesseract is slow but not too slow. I wrote a multi-threaded wrapper around the Rust bindings und a Python wrapper around that. Granted it is not very polished and I apparently forgot to make the Rust repository public but it works. The previous version of the project for which I made this wrote the image to disk and called the tesseract binary which took half a minute for a few of images. Definitely not usable for real-time processing. Now it takes around 200-300 ms with 12 worker threads. I'm not sure if there is further potential to make it faster though.

I don't like maturin workflow either because it installs directly to the python environment. This is not very useful during development. I wrote a module import file which loads the python module from the shared library. You could easily invoke cargo before importing the module (remember to delete the previous shared library file) to have a fully automated development processes.
