= note: the question mark operation (`?`) implicitly performs a conversion on the error value using the `From` trait
= help: the following implementations were found:
<i32 as From<NonZeroI32>>
<i32 as From<bool>>
<i32 as From<i16>>
<i32 as From<i8>>
and 2 others
<TryFromSliceError as From<Infallible>>
= note: required by `from`

error[E0271]: type mismatch resolving `<Result<i32, i32> as Try>::Ok == &str`
