You implemented a trait, overriding one or more of its associated types but did
|
||||
not reimplement its default methods.
|
||||
|
||||
Example of erroneous code:
|
||||
|
||||
```compile_fail,E0399
|
||||
#![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!
|
||||
}
|
||||
```

The length of the platform-intrinsic function `simd_shuffle`
|
||||
wasn't specified. Erroneous code example:
