How to use the calculator.rs?

[kw-andy]

I'm trying to use the calculator.rs but there is nothing explicitly written in the file. Is there something like a README.md on how to use it?

Thank you.

I believe rust default would be cargo run --example calculator.

But i am not able to run it - it crashes.

It would be:

cd examples && cargo run --release --bin calculator

@genofire This is likely a problem with your graphics drivers. Right now software rendering is not possible, so rendering will fail if the graphics drivers are too old.
