Some more helpful examples for the Rust WASM example?

[harshhhdev]

If I'm not mistaken, there are currently only two examples of how to use Rust WASM with Vercel's edge network. I think it'd be both beneficial to builders and Vercel if there are more examples featuring how to fetch data from distributed databases (eg. CockroachDB) or even fetching data from APIs.

In my opinion, the current examples seem rather confusing and it still makes this feature obscure to most users. The WASM code looks especially intimidating, hence why I think some more coherent examples which cover a wider array of applications would be beneficial.
