Question about codelens

[augustocdias]

I'm migrating from rust-tools to rustacean and I'm seeing the following error:

ERROR method textDocument/codeLens is not supported by any of the servers registered for the current buffer

I have the following autocmd that I set for all buffers when a LSP client attaches to it:

        if client.server_capabilities.code_lens or client.server_capabilities.codeLensProvider then
            local group = augroup('LSPRefreshLens')

            -- Code Lens
            autocmd({ 'BufEnter', 'InsertLeave' }, {
                desc = 'Auto show code lenses',
                buffer = bufnr,
                command = 'silent! lua vim.lsp.codelens.refresh()',
                group = group,
            })

Is this a problem with rust analyzer? I see this only with rust. The other LSP that also support codelens don't throw this error.

Should I not do that for rust?

Nevermind... Just saw in the docs that without specifying the buffer it will try for all buffers which might include ones without support for it...
