// This test is meant to test that we can have a stable item in an unstable module, and that
|
||
|
|
// calling that item through the unstable module is unstable, but that re-exporting it from another
|
||
|
|
// crate in a stable module is fine.
|
||
|
|
//
|
||
|
|
// This is necessary to support moving items from `std` into `core` or `alloc` unstably while still
|
||
|
|
// exporting the original stable interface in `std`, such as moving `Error` into `core`.
