syntax error in VSCode debug console

[Okroshiashvili]

OS: macOS Ventura
VSCode version: 1.76.2
CodeLLDB version: 1.9.0
Compiler: rustc
Debuggee: rust library

Maybe someone already asked/solved this issue. I'm not even sure it is issue. However, I tried really hard to figure out what's wrong with my debugger console.

Here are my VSCode settings.json, launch.json, and task.json

setting.json

{
    "lldb.displayFormat": "auto",
    "lldb.showDisassembly": "auto",
    "lldb.dereferencePointers": true,
    "lldb.consoleMode": "evaluate",
    "debug.allowBreakpointsEverywhere": true
}

tasks.json

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "cargo",
			"command": "build",
			"problemMatcher": [
				"$rustc"
			],
			"group": "build",
			"label": "rust: cargo build"
		}
	]
}

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lldb",
            "request": "launch",
            "name": "Rust Debug",
            "program": "${workspaceFolder}/target/debug/lib.rs",
            "args": [],
            "cwd": "${workspaceFolder}",
            "sourceLanguages": ["rust"]
        }
    ]
}

My issue:

When I start debugging, everything works just fine until I open debug console and will try to run some code. Here is an example

So, what's wrong with this?

The simple expressions evaluator does not support function calls. In general, you should not expect great REPL capabilities when debugging programs written in a compiled language.

Thank @vadimcn a lot. Was not aware of that
