Question: Inlay hints

[ghost]

I just setup coc-rust-analyzer and it works just fine.
I wonder if the extension is able to provide inlay hints out of chaining calls :

On the image above, the extension provide inlay hints for chaining calls but variables string and frequency do not have inlay hints.

Example with VSCODE

Did I miss one configuration to enable this feature ?
Thanks for your help.

You don’t missed anything, coc-rust-analyzer doesn’t support this, because we can’t do this in vim/neovim. #8 #177 (comment)
