A private trait was used on a "public" type. Erroneous code example:
|
||||
|
||||
```
|
||||
trait Foo {
|
||||
fn dummy(&self) { }
|
||||
}
|
||||
|
||||
pub trait Bar : Foo {} // error: private trait in exported type parameter bound
|
||||
```
|
||||
|
||||
To solve this error, please ensure the trait is accessible at the same level of
|
||||
the type(s) on which it's implemented. Example:
|
||||
|
||||
```
|
||||
pub trait Foo { // we set the Foo trait public
|
||||
fn dummy(&self) { }
|
||||
}
|
||||
|
||||
pub trait Bar : Foo {} // ok!
|
||||
```
