I've been using the previous version for months. Underneath Rend3, which handles some of the queuing and threading issues for Wgpu. Not for a web client; for complex 3D content on Linux. It's working well. With the new version, I should be able to cross-compile Rust to Windows as well as Linux, and generate a Windows executable without having to use any Microsoft products.
Long subject. Short version: for server-side webcrap, use Go.
All the standard parts needed for that are in good shape.
For complicated stuff with real-time or graphics aspects, use Rust.
