Is there a way to disable textDocument/onTypeFormatting from rust-analyzer?

I notice that rust-analyzer recently got some "assists" that hinder me more than help: https://github.com/rust-lang/rust-analyzer/blob/master/crates/ide/src/typing.rs#L42 - these all emit textDocument/onTypeFormatting events, which have been extremely disruptive to my editing of source code (inserting extra ; and } chars in places where I have to hunt for them, etc).

Is there a way to turn those off? Apparently, VS Code has the setting "editor.formatOnType" - is there a corresponding one in eglot?

Answering my own question - eglot-ignored-server-capabilities has a setting for this!

(add-hook 'rust-ts-mode-hook
          (defun asf--turn-off-rust-on-type-formatting ()
            (setq-local eglot-ignored-server-capabilities
                        (cons :documentOnTypeFormattingProvider
                              eglot-ignored-server-capabilities))))

Is what I ended up doing, and it works nicely. Phew!
