env::args().collect(); 251/562Rust 程序设计语言 简体中文版 let query = &args[1]; let file_path = &args[2]; println!("Searching for {query}"); println!("In file {file_path}"); } 示例 12-2：创建变量来存放查询参数和文件路径参数 时所看到的，程序的名称占据了 vector 的第一个值 args[0]，所以我 们从索引为 1 的参数开始。minigrep 获取的第一个参数是需要搜索的字符串，所以将第一个 参数的引用存放在变量 query 中。第二个参数将是文件路径，所以将第二个参数的引用放入变 量 file_path 中。 我们将临时打印出这些变量的值来证明代码如我们期望的那样工作。使用参数 test 和 sample.txt 函数处理的独立任务也会增加。当函数承担了更多责任，它就更难以 推导，更难以测试，并且更难以在不破坏其他部分的情况下做出修改。最好能分离出功能以便 每个函数各司其职。 这同时也关系到第二个问题：query 和 file_path 是程序中的配置变量，而像 contents 则用 来执行程序逻辑。随着 main 函数的增长，就需要引入更多的变量到作用域中，而当作用域中 有更多的变量时，将更难以追踪每

to computing, calculating or counting patents. Google patents data changes somewhat between each query so numbers are rounded and should be viewed as directionally accurate. Source: USA Patent & Trademark and video into a shared representation and generate outputs in any of those formats. A single query can reference a paragraph and a diagram, and the model can respond with a spoken summary or an annotated structured report draft; and an analyst can combine charts, transcripts, and audio clips in a single query. Compared with text-only models, multimodal systems cut context switching, capture richer detail

both structured analytics, full-text search and AI search (e.g., vector embeddings) requires hybrid query capabilities. Supporting Multiple Workloads Real-Time UDLs seamlessly handle real-time analytics systems. The native SQL support also makes it simple to use as it provides a single and easy way to query the data. 4. Why Do You Need a Real-Time Unified Data Layer? 65. CrateDB: a Modern Real-Time Unified
