Virtual text diagnostics is missing

Plz have a look at the screenshot below, left-side is the source code without showing the virtual text diagnostics, on the right side is cargo watch result:

Here is the result of :CocCommand rust-analyzer.serverVersion:

Here is the result of :CocUpdate:

Here is my :CocConfig:

{
    // make the completion automatically select the first completed item
    "suggest.noselect": false,

    // Hide the indicator as it looks weird
    "suggest.snippetIndicator": " ",

    // Not trigger completion on `string` and `comment`, but don't know why it doesn't work :(

And the funny thing is that it can show mismatched-arg-count error…and seems only can show this kind of the error:

coc-rust-analyzer and rust-analyzer both are the latest version, and it works before, totally have no idea what’s happening.

Also, the diagnostics error can show for another language like TypeScript etc, only doesn’t work on Rust…

Caused by "rust-analyzer.checkOnSave.enable": false.

rust-analyzer.enableCargoWatchOnStartup

This is a very old configuration https://github.com/rust-analyzer/rust-analyzer/pull/2668/files#diff-00784dde03b1be151004f435a4ca74754cb674a9e789840e12760d8f3ac1728fL201

Any idea or suggestion that can get around that block & wait

Have no idea about this, maybe you can ask rust-analyzer team, coc-rust-analyzer does same as vscode-rust-analyzer.
