pub enum CastKind {

Transmute(Ty, Ty),
}
Expand description
For all the variants: the first type gives the source type, the second one gives the destination type.
Variants§
Scalar(LiteralTy, LiteralTy)
Conversion between types in {Integer, Bool} Remark: for now we don’t support conversions with Char.
RawPtr(Ty, Ty)
FnPtr(Ty, Ty)
Unsize(Ty, Ty)
Unsize coercion. This is
either [T; N]
-> [T]
or T: Trait
-> dyn Trait
coercions, behind a pointer
(reference, Box
, or other type that implements CoerceUnsized
).
The special case of &[T; N]
-> &[T]
coercion is caught by UnOp::ArrayToSlice
.
Transmute(Ty, Ty)
Reinterprets the bits of a value of one type as another type, i.e. exactly what
std::mem::transmute
does.
