Parameters: uri (str) – URI or part of a URI to encode. If this is a wide string (i.e., six.text_type), it will be encoded to a UTF-8 byte array and any multibyte sequences will be percent-encoded

RcWeak 可以同时存在，例如： { let six = Rc::new(vec![1,2,3,4]); let six2 = six.clone(); let six3 = six.clone(); let six3 = Rc::downgrade(&six3); //output //[1 //six3 is (Weak) println!("{:?}",six); println!("{:?}",six3); drop(six); drop(six2); //no compile error println!("six3 is {:?}",six3); } 可以看到，即使 six 和 six2 释放，six3 存在，编译时没有仍然没有报错。并 且打印结果是 six3 is (Weak)。 6.5.1.2 Arc 与 Arc Weak 首先引出 Arc 前先罗列一个例子。搭配 mutex 进行使用，对共享内存中的内容 进行修改。 use std::sync::{Mutex, Arc}; use std::thread;

impediments3 A release comprises a series of sprints. As an example, consider Figure 2, which depicts a six-month release with a series of one-month sprints. During each sprint, a daily scrum meeting takes military capabilities to the operational community. This guide recommends that DoD programs consider six months as the release timeframe. Many private sector companies using Agile techniques deploy capabilities program. Figure 9 shows a six-month release that could include five monthly sprints followed by a month for final testing and certification. Figure 9: Potential Six-Month Release Structure

is the latest installment in the largest and longest-running project of its kind, pulling together six years of data drawn from over 31,000 technology professionals worldwide. It charts the performance businesses report correspondingly low deployment frequencies, ranging between once a month and once every six months. 2. Lead time for code changes This metric refers to the average time from check-in to production than a day. Businesses that are not performing well reported an average lead time of between one and six months. 3. Time to restore service This is defined by DORA as the average time from the detection
