This breaks code like:
struct Foo {
...
}
pub fn make_foo() -> Foo {
...
}
Change this code to:
pub struct Foo { // note `pub`
...
}
pub fn make_foo() -> Foo {
...
}
The `visible_private_types` lint has been removed, since it is now an
error to attempt to expose a private type in a public API. In its place
a `#[feature(visible_private_types)]` gate has been added.
Closes #16463.
RFC #48.

# ICE when returning struct with reference to trait
|
|
|
|
A function which takes a reference to a trait and returns a
|
|
struct with that reference results in an ICE.
|
|
|
|
This does not occur with concrete types, only with references
|
|
to traits.
