Variants

`ErrorGuaranteed`

`CastToBool`

`CastToChar`

`DifferingKinds`

`SizedUnsizedCast`

Cast of thin to fat raw ptr (e.g., *const () as *const [u8]).

`IllegalCast`

`NeedDeref`

`NeedViaPtr`

`NeedViaThinPtr`

`NeedViaInt`

`NonScalar`

`UnknownExprPtrKind`

`UnknownCastPtrKind`

`IntToFatCast(Option<&'static str>)`

Cast of int to (possibly) fat raw pointer.

Argument is the specific name of the metadata in plain words, such as “a vtable” or “a length”. If this argument is None, then the metadata is unknown, for example, when we’re typechecking a type parameter with a ?Sized bound.

`ForeignNonExhaustiveAdt`
