Printing Traceback #4395

When using RustPython for embedded scripting purposes, I want to be able to print out the traceback if the input fails. Currently I am using this function: use rustpython::vm;
pub fn run_py(code: &str, filename: &str) {
match vm::Interpreter::with_init(Default::default(), |vm| {
vm.add_frozen(rustpython_pylib::frozen_stdlib())
})
.enter(|vm| {
let scope = vm.new_scope_with_builtins();
let code_obj = vm
.compile(code, vm::compiler::Mode::Exec, String::from(filename))
.map_err(|err| vm.new_syntax_error(&err))?;
return vm.run_code_obj(code_obj, scope);
}) {
Ok(_) => {}
Err(e) => {
println!("{:?}", e.traceback().unwrap()); // !!!HERE!!!
}
};
