|
LL | (T::from(from), ())

|
| ^^^^^^^^^^^^^^^^^^^ expected `dyn Span`, found `(T, ())`

= note: expected trait object `(dyn Span<T> + 'static)`
|

found tuple `(T, ())`
|
|
= help: `(T, ())` implements `Span` so you could box the found value and coerce it to the trait object `Box<dyn Span>`, you will have to change the expected type as well
|
|
help: call `Into::into` on this expression to convert `(T, ())` into `(dyn Span<T> + 'static)`

|
|
LL | (T::from(from), ()).into()
