I use rust for commercial projects because I can specify the language and sometimes rust is the right language (most of the time python is the right language). I was hired into this role many years ago as a PHP developer. And we haven't needed rust devs. So I have no experience with the rust job marketplace.

I also have a lot of personal pet projects written in rust: an MMORPG-style game, accounting software, various WASM widgets, some OS fiddling, some work extending servo as a browser that implements umatrix-like control but lets you set options per domain (e.g. 3rd party cookie, user agent setting, etc, all per-domain).

I've also contributed a number of small libraries that I wrote for my projects to open source (textnonce, float-cmp, mailstrom, formdata, mime-multipart, solvent, ddsfile, pemmican, resolv-rs, email-format, and others).
