有句话叫,学习 Rust 一点都不难,我学过好多次了。最近有时间再学一遍,比较了几本书:《Rust 编程之道》《Programming Rust》《Programming Rust, 2nd Edition》《Rust 程序设计(第2版)》《Rust 程序设计》(本文不是一篇书评,是几本书的横评)《Rust 编程之道》最开始从《Rust 编程之道》读起,这还是我多年前...
Pythons’ constant popularity has been revealed through industry-leading programming usage surveys. For instance, the 2020 Stack Overflow Developer Survey revealed that Python is the third most popular language worldwide, and Rust was not even close to it. Interestingly, Python was also able to ...
The biggest worries for the future of Rust among users are too much complexity and too little usage in the tech industry, the 2023 State of Rust Survey finds.
1.81 stabilizes the Error trait in core, allowing usage of the trait in #![no_std] libraries. This primarily enables the wider Rust ecosystem to standardize on the same Error trait, regardless of what environments the library targets. New sort implementations Both the stable and unstable sort ...
In Part 1 of this blog series, we dug into our list of the top 10 most common Rust compiler errors according to RustRover’s usage data, and we made it halfway through the list. In this part, we’ll exp
