1 error[E0423]: expected value, found trait `SomeTrait`
4 LL | let trait_obj: &dyn SomeTrait = SomeTrait;
5 | ^^^^^^^^^ not a value
7 error[E0038]: the trait `SomeTrait` cannot be made into an object
10 LL | let trait_obj: &dyn SomeTrait = SomeTrait;
11 | ^^^^^^^^^^^^^^ `SomeTrait` cannot be made into an object
13 note: for a trait to be "object safe" it needs to allow building a vtable to allow the call to be resolvable dynamically; for more information visit <https://doc.rust-lang.org/reference/items/traits.html#object-safety>
16 LL | trait SomeTrait {
17 | --------- this trait cannot be made into an object...
19 | ^^^ ...because associated function `foo` has no `self` parameter
20 help: consider turning `foo` into a method by giving it a `&self` argument
24 help: alternatively, consider constraining `foo` so it does not apply to trait objects
26 LL | fn foo() where Self: Sized;
