Creating a mock with multiple traits fails if traits share a name

[discosultan]

In mockall = "0.13":

use mockall::mock;

mod a {
    pub trait A {
        fn foo(&self);
    }
}

mod b {
    pub trait A {
        fn bar(&self);
    }
}

mock! {
    // Structure to mock
    C {}
    // First trait to implement on C
    impl a::A for C {
        fn foo(&self);
    }
    // Second trait to implement on C
    impl b::A for C {
        fn bar(&self);
    }
}

fails with:

error[E0428]: the name `__mock_MockC_A` is defined multiple times
  --> src/lib.rs:15:1

Ahh yes. That's bound to cause problems. I bet if you expand the code, you'll find more than just those two identically named structs, too. This limitation is unlikely to be fixed. But if it's really important to you, you could take a stab at it. Perhaps you could name the structs using the full path to the trait, replacing :: with __ ?

I gave it a go in #601.

Fixed by #601
