So clearly Rust is ready for tiling window managers. When will Rust be ready for the web (at least to the level of where Go is right now) ?
The next issue, if we're talking about high-performance http is asynchronous I/O which Rust doesn't currently bundle with (now that Rust has dismantled it's green threading runtime and is now sticking with native threading). However, mio [2], a lower-level Rust library in providing proper I/O abstractions that support async apis and the like is progressing pretty well.
The awesome part about Rust is that you have full control over the system. This allows one to build something like mio even though Rust doesn't support async I/O or a more efficient threading model, etc...
