Initializing a Rust variable passed to async code such as tokio and hyper

问题 I have a value that cannot be computed at compile time. It needs to be computed before any of the app code runs, and then it will only be read throughout the lifetime of the app. It also needs to be passed around to executors such as tokio and hyper handlers. How can I create such a value safely, idiomatically and without unneeded performance losses? If I create it in main and pass it to hyper , it does not live long enough. If I create it with lazy_static! , it only gets computed when it's

问题 I have a project with microservices deployed in Bluemix with Docker containers. All microservices are written in Java and the communication is using JKS files. I also developed a microservice in Node.js with Express.js. To consume the other microservices, I used the Request module with option.agentOptions feature and a pfx file , like this: var options = { uri: config.get("https://www.example.com/ms/service"), method: 'POST', body: data, json: true, headers: { 'Content-Type': 'application

How do I share a HashMap between Hyper handlers?

问题 I'm attempting to learn Rust by implementing a simple in-memory URL shortener with Hyper 0.10. I'm running into an issue that I think is caused by trying to close over a mutable HashMap in my handler: fn post(mut req: Request, mut res: Response, short_uris: &mut HashMap<&str, &str>) { let mut body = String::new(); match req.read_to_string(&mut body) { Ok(_) => { let key = short_uris.len(); short_uris.insert(&key.to_string(), &body.to_string()); *res.status_mut() = StatusCode::Created; res

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 转载请在文首保留原文出处： EMC中文支持论坛 https://community.emc.com/go/chinese 介绍现如今重复数据删除已成为一种存储主流技术。如何在形形色色的重复数据删除解决方案中找到最合适的一款，是IT专业人员面临的难题。在 Windows Server 2012 的存储新功能——重复数据删除这篇文章中，我们介绍过最新的Windows Server 2012操作系统自带有重复数据删除功能。那么我们究竟是该使用Windows Server 2012操作系统自带的重复数据删除功能呢还是该把重复数据删除的任务交给备份软件来完成呢？这个问题恐怕很难有100%确切的答案，不过我们可以从下面这些因素来考虑。更多信息 1. 重复数据删除的目标是什么？首先要考虑的是为什么要重复数据删除，目的何在。源端重复数据删除的主要目的通常不是降低服务器上的存储数据量，而是减少需要传输到备份服务器上进行存储的数据量。 Windows Server 2012自带的重复数据删除功能也是一种源端重复数据删除，但是它的主要目的是为了减少服务器存储空间的消耗，而不是减少备份的数据量（至少对它自己本身而言不是）。当然，你可能会问这样一个问题：是否可以将Windows Server
