let my_vec = ["foo", "bar", "baz", "foobar", "barfoo"];
let mut curr_obj = object!();

// add part of path to te path gotten from fn get_exe_path();
fn get_file_path(path_to_file: &str) -> PathBuf {

我想,而不调用它们都匹配多个函数的结果,如果没有必要: fn foo() -> bool {
println!("foo executed");
true
}
// I want to do something like this
// but there is a redundant function call
match (foo(), foo()) {
