How to make Rust Analyzer to check on the fly when you type?

[yesint]

I'm trying Zed editor to develop Rust project and it work perfectly except one annoying thing: I can't configure Rust Analyzer to run checks when I type, like it does in VS Code.
For me Rust Analyzer re-checks only on save in Zed and I can't find anywhere how to configure it to do this on the fly when I type.
Anybody knows how to do this?
