Enum CastKind

source
pub enum CastKind {
    Scalar(LiteralTy, LiteralTy),
    RawPtr(Ty, Ty),
    FnPtr(Ty, Ty),
    Unsize(Ty, Ty),
    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.
