'a' ran for 30ms 'a' ran for 10ms 'a' ran for 20ms 'b' started. 'b' ran for 75ms 'b' ran for 10ms 'b' ran for 15ms 'b' ran for 350ms 'a' finished. 与上一个示例一样，race 仍然在 a 完成后就立刻结束了。两个 程序设计语言 简体中文版 let one_ms = Duration::from_millis(1); let a = async { println!("'a' started."); slow("a", 30); trpl::sleep(one_ms).await; slow("a"

be delayed and/or combined to minimize the number of packets sent. This can sometimes cause 200-500ms delays due to the interaction between Nagle’s algorithm and TCP delayed ACKs. To reduce this delay (for more information, see http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTCONNECTTIMEOUT MS and comments in curl_httpclient.py).
