struct S{data:String,
}//注意：因為String默認是移動語義，從而決定結構體S也是移動語義，可采用(1)或(2)兩種方法解決編譯錯誤；關鍵思路：放棄獲取結構體S的字段data的所有權，改為借用。fn process(s_ref:&S){//&S ，借用match *s_ref { //S ， 值//(1) match s_ref { //&S ， 借用//(2) S{ref data} => { //data:&String ， 借用S{data} => { //出錯點.println!("Data: {}",data);},// _ => {},}
}fn main(){let s = S{data:String::from("hello world"),};process(&s);
}
