The Rust ecosystem is still iterating on what the best patterns for defining custom error types and chaining nested errors are, so I expect this space to continue to improve in the near future. I mentioned previously that we’re using the jni and cbindgen crates to help with our FFI ...

在Rust的编译器代码中,rust/compiler/rustc_infer/src/traits/error_reporting/mod.rs文件的作用是提供类型推断中错误报告相关的功能。 该文件中的代码负责生成和显示与类型推断相关的错误和警告信息。它通过定义多个trait和实现它们来完成这一任务。 以下是几个trait的作用: ...
I assume the app would be built asno_stdso we'd need to provide (generate on the fly perhaps) bindings to Zephyr's kernel std handlers. All the generators would have to be integrated either with Zephyr's cmake build flow, or as a custom rust create build (whatever is more convenient...
