Rust Load Generator around postman collection

I am writing a tool in Rust which can take a postman collection and environment file and generate load using that collection. Challenge I am facing is handling test scripts section of request.
I do not wish to spend time building js parser for rust.

Is it possible to build plugins around postman? Where I can take input regarding post processing on response to extract data and make it available for next requests?

The Javascript processing is done within separate node module called postman-sandbox.

Having said that, sadly we haven’t reached the point yet where we can easily plug in an external requesting mechanism. But perhaps @udit.vasu can share some ideas.
