Please add text as text, not as an image. Actual text is much easier to read than text in an image. Thanks.

Thanks for your remind, already updated in original post

Your program is aborting in __rust_foreign_exception. Most likely, this means that your code had an exception in C++ code that was not caught, so it unwinded into Rust code.

thx for ur reply, but why would a c++ exception is caught by rust? And is there any way to confirm that?

[Darksonn]

Your code or one of your dependencies is probably calling into C++ incorrectly. It's unlikely to be a bug in Tokio.

Yeah, but I can't figure out why a c++ exception is caught by rust? Should it be caught by c++? And if there any advice to capture more accurate exception message? Thanks!

[Darksonn]

Generally, C++ exceptions must be caught in C++. They should not unwind into Rust code.

Generally, C++ exceptions must be caught in C++. They should not unwind into Rust code.

It turns out that my c++ code runs in async runtime and throws an exception. Thx for ur help!
