为什么我们为Capture建立了一个定制的Rust库

Dropbox Capture is a new visual communication tool designed to make it easy for teams to asynchronously share their work using screen recordings, video messages, screenshots, or GIFs. There's no formal onboarding required, and you can start sharing your ideas in seconds. In fact, simplicity is key to the Capture experience, and it's a value that also extends down to the development of Capture’s underlying code. 

Dropbox Capture是一个新的视觉交流工具，旨在使团队能够轻松地使用屏幕记录、视频信息、屏幕截图或GIF来异步分享他们的工作。不需要正式的入职培训，你可以在几秒钟内开始分享你的想法。事实上，简单性是Capture体验的关键，这种价值也延伸到Capture底层代码的开发中。

One of our team’s guiding principles is “be a Margherita pizza.” Just as a Margherita pizza is perfect in its simplicity—what more do you need than tomato sauce, mozzarella, and basil?—we’ve tried to keep Capture’s ingredients as simple and straightforward as possible. We knew early on that Electron and Node would make it easy to build a cross-platform TypeScript app for both macOS and Windows. But finding the right third ingredient that would enable us to quickly, simply, and reliably call native OS-level code took a bit more experimentation.  

我们团队的指导原则之一是 "做一个玛格丽特比萨"。正如玛格丽特披萨的完美之处在于其简单性--除了番茄酱、马苏里拉奶酪和罗勒，你还需要什么呢？我们很早就知道，Electron和Node会让我们很容易为macOS和Windows建立一个跨平台的TypeScript应用。但要找到合适的第三种成分，使我们能够快速、简单和可靠地调用原生操作系统级代码，则需要进行更多的试验。

Ideally, we wanted streamlined a codebase that could target multiple platforms painlessly, consistently, and that was easy for our developers to build. We also wanted more control over our ability to take screen captures and recordings, better error handling, and faster performance behind the scenes. In fact, we were looking for something that would give us more control at every layer—that didn’t require us to jump through quite so many hoops to call native code—and would better support the new features we wanted to build.

理想情况下，我们想要一个精简的代码库，能够无痛地、一致地针对多个平台，并且便于我们的开发人员构建。我们还希望对屏幕捕捉和录音的能力有更多的控制，更好的错误处理，以及更快的幕后性能。事实上，我们正在寻找一种能在每一层都给我们更多控制的东西--它不需要我们跳过那么多圈来调用本地代码--并且能更好地支持我们想要建立的新功能。

There were a lot of ways we could have solved these problems—...
