Diagnostic Errors Not Showing Up

[Sotatek-TruongNguyen2]

I'm trying rustaceanvim to enhance my Rust coding experience, but I've realized that Rust Analyzer is only able to show syntax-related errors. So if my error is related to borrow checker, the diagnostic will not appear. Here's my rust-analyzer configuration in neovim:

default_settings = {
                    -- rust-analyzer language server configuration
                    ['rust-analyzer'] = {
                        diagnostics = {
                            enable = true,
                            -- enableExperimental = true,
                        },
                        cargo = {
                            allFeatures = true,
                            -- buildScripts = {
                            --     enable = true,
                            -- },
                        },
                        -- procMacro = {
                        --     enable = true
                        -- },
                         -- Clippy
                        checkOnSave = {
                            command = "clippy", -- Run Clippy on save
                        },
                    },
                },
