講解內容

1、通道與所有權轉移

（1）例子：

use std::thread;

use std::sync::mpsc;

fn main() {

let (tx, rx) = mpsc::channel();

thread::spawn(move || {

let val = String::from("hi");

tx.send(val).unwrap();

println!("val is {}", val);//錯誤，此處不能使用val，因為val的所有權已經move到通道里面去了

});

let received = rx.recv().unwrap();

println!("Got: {}", received);

}

2、發送多個值示例

use std::thread;

use std::sync::mpsc;

use std::time::Duration;

fn main() {

let (tx, rx) = mpsc::channel();

thread::spawn(move || {

let vals = vec![

String::from("hi"),

String::from("from"),

String::from("the"),

String::from("thread"),

];

for val in vals {

tx.send(val).unwrap();

thread::sleep(Duration::from_secs(1));

}

});

for received in rx {

println!("Got: {}", received);

}

}
