I know and I would also try Rust if I can make some small but useful things at work. But I mostly deal with various combinations of XML, SOAP, HTTP, LDAP etc. Rust does not have anything over Java, which I use currently, in my usecases.
It's perfectly reasonable to say "Rust isn't appropriate for my use case". Your comment higher up was more along the lines of "Rust isn't appropriate for anyone" which is far less reasonable.
If you're going to put words in his mouth, you should make them much stronger words. It's not a valid argument either way, but it'll seem more dramatic. (He didn't say either of your quotes...)
I have to deal with a pre-REST, pre-SOAP XML API, which I would love, love, to be able to handle in Rust. But until Serde-XML is able to deserialize more of that stuff and preferably handle XSDs, I'm stuck too.
