## Variants§

§

### SizedSelf(SmallVec<[Span; 1]>)

`Self: Sized` declared on the trait.

§

### SupertraitSelf(SmallVec<[Span; 1]>)

Supertrait reference references `Self` an in illegal location (e.g., `trait Foo : Bar<Self>`).

§

### SupertraitNonLifetimeBinder(SmallVec<[Span; 1]>)

§

### Method(Symbol, MethodViolationCode, Span)

Method has something illegal.

§

### AssocConst(Symbol, Span)

Associated const.

§

### GAT(Symbol, Span)

GAT

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
