error[E0277]: the trait bound `foo::Struct: Trait` is not satisfied
--> foo-current.rs:13:19
|
13 | check_trait::<foo::Struct>();
| ^^^^^^^^^^^ the trait `Trait` is not implemented for `foo::Struct`
|
note: there are multiple different versions of crate `foo` in the dependency graph
--> foo-current.rs:7:1
|
4 | extern crate foo;
| ----------------- one version of crate `foo` is used here, as a direct dependency of the current crate
5 |
6 | pub struct Struct;
| ----------------- this type implements the required trait
7 | pub trait Trait {}
| ^^^^^^^^^^^^^^^ this is the required trait
|
::: foo-prev.rs:X:Y
|
4 | pub struct Struct;
| ----------------- this type doesn't implement the required trait
5 | pub trait Trait {}
| --------------- this is the found trait
= note: two types coming from two different versions of the same crate are different types even if they look the same
= help: you can use `cargo tree` to explore your dependency tree
note: required by a bound in `check_trait`
--> foo-current.rs:10:19
|
10 | fn check_trait<T: Trait>() {}
| ^^^^^ required by this bound in `check_trait`
error: aborting due to 1 previous error
