One of my first pull requests after joining Fullstory was changing our error handling from error-chain (which was great when it first came out) to the more modern anyhow for general error handling and thiserror to define some specific errors in an enum. Rust’s powerful error handling, with...
“When it came to whether to finish the film or not, my decision really was, If the tables were turned, I would want her to finish the film,” Cline told Vulture on November 20. “I really try in my life to do everything according to what’s the right thing to do — not what...
when making the directory, if it exists already and is a symlink to a dir, or is a dir, use it, otherwise error when deleting the directory, if it is a symlink, unlink it, or if a directory, recursively delete with link-following-safety, otherwise error. I think remove_dir_all + t...
As I understand it, Haskell has this problem when you rely on type inference for top-level functions. Rust nipped that particular problem in the bud. 函数是防范改变代码带来影响的自然边界。如果我们允许从代码中完全的检查生命周期,那么一个看起来无害的改变可能会影响生命周期,导致远处的函数中出现错误。
so I was applying the relocations when they were already applied. It also seems like rustc now generates IMAGE_REL_AMD64_REL32 relocation types which are a bit annoying to understand. I referenced a few sources and came up with some code that seems to work. So it works again. I also ...
Bound::map File::create_new Mutex::clear_poison RwLock::clear_poison Other changes Check out everything that changed in Rust, Cargo, and Clippy. Contributors to 1.77.0 Many people came together to create Rust 1.77.0. We couldn't have done it without all of you. Thanks!赞...
Output viaBufWriter. This is needed for speed, if you want to write a large number of lines.BufWriterflushes automatically when it goes out of scope, but you'll probably want toflush()manually on interactive problems. Further I/O optimizations are possible (see comments section), but this ...
Remember those first few hours of Legacy Rust? Farming resources for your first big base, and needing a place to call home in the meantime? The shelter was the answer. Now it's back! The shelter comes with an included door, key lock and even a small radius of building privilege! The ...
In 2021, for the first time, more than half of all Rust programmers were using the language on the job. They weren’t just playing with Rust on the side anymore; they were using it to produce professional code for other people to run. Here’s a look at what developers tend to love,...
If the program relies on unspecified details of how data is laid out, it will still run fine in Miri -- but might break (including causing UB) on different compiler versions or different platforms. Program execution is non-deterministic when it depends, for example, on where exactly in memor...
