#### Note: this error code is no longer emitted by the compiler
You implemented a trait, overriding one or more of its associated types but did
not reimplement its default methods.
Example of erroneous code:
```
#![feature(associated_type_defaults)]
pub trait Foo {
type Assoc = u8;
fn bar(&self) {}
}
impl Foo for i32 {
// error - the following trait items need to be reimplemented as
// `Assoc` was overridden: `bar`
type Assoc = i32;
}
```
To fix this, add an implementation for each default method from the trait:
```
#![feature(associated_type_defaults)]
pub trait Foo {
type Assoc = u8;
fn bar(&self) {}
}
impl Foo for i32 {
type Assoc = i32;
fn bar(&self) {} // ok!
}
```
