Error code E0624

A private item was used outside of its scope.

Erroneous code example:

#![allow(unused)] fn main() { 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:
#![allow(unused)] fn main() { 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. }
  1. Make the item public:
#![allow(unused)] fn main() { mod inner { pub struct Foo; impl Foo { pub fn method(&self) {} // It's now public. } } let foo = inner::Foo; foo.method(); // Ok! }
