What's should be the return type for function
АГ
What's should be the return type for function
which function? can you use rust-playground to describe your problems precisely?
IB
Question mark operator can be used only in function that returns Resukt<...>.
V
Result<first, second>
AT
Result<first, second>
Yep. The
main function should return Result.V
But what should be first and second in that case
e🦀
Return type is Result<Value, Error>, not the first or second
В
But what should be first and second in that case
something like
Result<(), mongodb::Error>r
For
main it's better to use Result<(), Box<dyn std::error::Error>>, as it usually deals with many kinds of errorsВ
Also, it's Russian group, you may prefer English speaking one: https://t.me/rustdevs
