error[E0277]: the size for values of type `dyn ToString` cannot be known at compilation time

--> $DIR/issue-61525.rs:14:19
|
|
|
|
|
LL | 1.query::<dyn ToString>("")
|
|
| ----- ^^^^^^^^^^^^ doesn't have a size known at compile-time
|
|
| |
|
|
| required by a bound introduced by this call
|
|
|
|
|
= help: the trait `Sized` is not implemented for `dyn ToString`
|
|
note: required by an implicit `Sized` bound in `Example::query`

LL | 1.query::<dyn ToString>("")
|
|
| --------------------- ^^ expected `dyn ToString`, found `&str`
|
|
| |
|
|
| arguments to this method are incorrect
|
|
|
|
|
= note: expected trait object `dyn ToString`
|
|
found reference `&'static str`
|
|
= help: `&'static str` implements `ToString` so you could box the found value and coerce it to the trait object `Box<dyn ToString>`, you will have to change the expected type as well
|
|
note: method defined here
