``` error[E0277]: the trait bound `dep_2_reexport::Type: Trait` is not satisfied because the trait comes from a different crate version --> multiple-dep-versions.rs:7:18 | 7 | do_something(Type); | ^^^^ the trait `Trait` is not implemented for `dep_2_reexport::Type` | note: there are multiple different versions of crate `dependency` in the dependency graph --> /home/gh-estebank/rust/build/x86_64-unknown-linux-gnu/test/run-make/crate-loading/rmake_out/multiple-dep-versions-1.rs:4:1 | 3 | pub struct Type(pub i32); | --------------- this type implements the required trait 4 | pub trait Trait { | ^^^^^^^^^^^^^^^ this is the required trait | ::: multiple-dep-versions.rs:1:1 | 1 | extern crate dep_2_reexport; | ---------------------------- one version of crate `dependency` is used here, as a dependency of crate `foo` 2 | extern crate dependency; | ------------------------ one version of crate `dependency` is used here, as a direct dependency of the current crate | ::: /home/gh-estebank/rust/build/x86_64-unknown-linux-gnu/test/run-make/crate-loading/rmake_out/multiple-dep-versions-2.rs:3:1 | 3 | pub struct Type; | --------------- this type doesn't implement the required trait 4 | 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 ``` The approach to accomplish this is a HACK, and we'd want a better way to do this. I believe that moving E0277 to be a structured diagnostic would help in that regard. |
