Ian Jackson: Tricky compatibility issue - Rust's io::ErrorKind
This post is about some changes recently made to Rust's ErrorKind, which aims to categorise OS errors in a portable way.
[...]
The Rust programming language tries to make it straightforward to write portable code. Portable error handling is always a bit tricky. One of Rust's facilities in this area is std::io::ErrorKind which is an enum which tries to categorise (and, sometimes, enumerate) OS errors. The idea is that a program can check the error kind, and handle the error accordingly.
That these ErrorKinds are part of the Rust standard library means that to get this right, you don't need to delve down and get the actual underlying operating system error number, and write separate code for each platform you want to support. You can check whether the error is ErrorKind::NotFound (or whatever).
Because ErrorKind is so important in many Rust APIs, some code which isn't really doing an OS call can still have to provide an ErrorKind. For this purpose, Rust provides a special category ErrorKind::Other, which doesn't correspond to any particular OS error.
