1 error[E0308]: `?` operator has incompatible types
2 --> $DIR/issue-71309.rs:2:18
5 | ^^ expected `u32`, found `i32`
7 = note: `?` operator cannot convert from `i32` to `u32`
8 help: you can convert an `i32` to a `u32` and panic if the converted value doesn't fit
10 LL | let y: u32 = x?.try_into().unwrap();
11 | ++++++++++++++++++++
13 error: aborting due to previous error
