Recently I have been working on making it possible to fuzz Soroban contracts. Having some progress and experience now, I am writing up what I have learned and prototyped in hopes of getting feedback.
The work is currently done in the arbitrary branches of three forks:
Hi, everyone! Super happy to reach out to you! As a Rustacean, I’ll be grateful for your advice. Due to the war in Ukraine, I’m working on becoming a junior Rust software engineer ASAP. As an anti-corruption activist, I have to relocate from Russia. Because of the war, I’ve lost my family & my livelihood.
But I’m not here to tell a sob story, I’m here to ask the practical questions. I could start my new career as a JavaScript front end guy, but JS doesn't suit my personality, while Rust does. With Rust, I’ll love my work, but with JS — less so.
Unless it’s impossible to go from 0 to a Rust junior job in 1-2 years or faster, I would do everything to choose Rust over JS.

Some notes about the question "who is actually using Rust?".
Firefox
Dropbox's storage backend is in Rust, probably other components as well
Reddit uses Rust on every request for markdown parsing
| crates.io has https://github.com/rust-lang/crates.io/blob/master/docs/MIRROR.md as some loose docs and I believe there exist tools to sort of manage it for you and also mirror s3, but not sure | |

| static.rust-lang.org measures in the dozens of terabytes range so I don't know if a mirror is really practical to maintain, nor am I sure if it'd be helpful as s3 seems fairly reliable |
