Rust anyhow Library: Simplifying Error Handling Error handling is a crucial aspect of building robust software. In Rust, while the standard library provides powerful tools for managing errors using Result and Option, managing complex error hierarchies or propagating errors from multiple sources can be ...
Error Handling Libraries::Rust 也有几个错误处理库,例如标准库的 Error 特征和流行的 crates,如 thiserror、anyhow 和 failure,它们为错误处理提供了更高级的功能,例如自定义错误类型、回溯和错误链接。 3、标准库在 Rust 中的作用是什么?Rust 中的标准库包含提供该语言核心功能的模块集合。标准库随 Rust 的每次...
Error-chain Github crates.io 前言 错误和异常傻傻分不清,这里统称为错误吧。Rust 错误分为两大类:可恢复和不可恢复的错误。 可恢复的错误,例如一个文件没有发现错误,这时合理的向用户报告的问题和重试操作。 不可恢复的错误总是就是不可恢复了,比如数组的越界访问。 大多语言,例如在c++对上述两类错误没有严...
Ever since theErrortrait landed in Rust, the community settled on two crates:thiserrorandanyhow. thiserroris a derive macro that simplifies the implementation of theErrortrait on user types and is supposed to be used mainly in abstractions. anyhowis a crate that provides an opaqueanyhow::Errort...

We need to start leveraging the error handling machinery exposed byactix_web- in particular,actix_web::Error. According to the documentation: actix_web::Erroris used to carry errors fromstd::errorthroughactix_webin a convenient way. It sounds exactly like what we are looking for. How do we...
Use the thiserror and anyhow crates for idiomatic error handling. You should use thiserror when the consumer needs to conditionally act based on the error, anyhow otherwise. A good guideline is “use thiserror for libraries and anyhow for applications”. Using dbg!() macro instead of println...
the most part, this meant we could implement native components in the most straightforward way, and avoid pain where Rust didn’t have a good interface to the platform. We have a set of Rust packages (in Rust lingo, “crates”) in acargo workspacethat divide things up into logical pieces...
