io::Error::into_inner
returns an Option<Box<dyn Error + ..>>
right now, but it should presumably return Result<Box<dyn Error + ..>,Self>
like other consuming methods. Am I missing something here?
The only other data which an io error can have is the kind, so if you wanted a lossless destructure you can do (err.kind(), err.into_inner())
. There no owned data attached to the error if into_inner
returns None
, and I expect that's why it was stabilized as returning Option
.
It might've been more "correct" to return a result, but this is the signature that we've got.
