Error code E0445
Note: this error code is no longer emitted by the compiler.
A private trait was used on a public type parameter bound.
Previously erroneous code examples:
trait Foo { fn dummy(&self) { } } pub trait Bar : Foo {} // error: private trait in public interface pub struct Bar2<T: Foo>(pub T); // same error pub fn foo<T: Foo> (t: T) {} // same error fn main() {}
To solve this error, please ensure that the trait is also public. The trait
can be made inaccessible if necessary by placing it into a private inner
module, but it still has to be marked with pub
. Example:
pub trait Foo { // we set the Foo trait public fn dummy(&self) { } } pub trait Bar : Foo {} // ok! pub struct Bar2<T: Foo>(pub T); // ok! pub fn foo<T: Foo> (t: T) {} // ok! fn main() {}
