A private item was used outside of its scope.
Erroneous code example:
```compile_fail,E0624
mod inner {
pub struct Foo;
impl Foo {
fn method(&self) {}
}
}
let foo = inner::Foo;
foo.method(); // error: method `method` is private
```
Two possibilities are available to solve this issue:
1. Only use the item in the scope it has been defined:
```
mod inner {
pub struct Foo;
impl Foo {
fn method(&self) {}
}
pub fn call_method(foo: &Foo) { // We create a public function.
foo.method(); // Which calls the item.
}
}
let foo = inner::Foo;
inner::call_method(&foo); // And since the function is public, we can call the
// method through it.
```
2. Make the item public:
```
mod inner {
pub struct Foo;
impl Foo {
pub fn method(&self) {} // It's now public.
}
}
let foo = inner::Foo;
foo.method(); // Ok!
```
