Variants

PointerExposeAddress

An exposing pointer to address cast. A cast between a pointer and an integer type, or between a function pointer and an integer type. See the docs on expose_addr for more details.

PointerFromExposedAddress

An address-to-pointer cast that picks up an exposed provenance. See the docs on from_exposed_addr for more details.

PointerCoercion(PointerCoercion)

Pointer related casts that are done by coercions. Note that reference-to-raw-ptr casts are translated into &raw mut/const *r, i.e., they are not actually casts.

DynStar

Cast into a dyn* object.

IntToInt

FloatToInt

FloatToFloat

IntToFloat

PtrToPtr

FnPtrToPtr

Transmute

Reinterpret the bits of the input as a different type.

MIR is well-formed if the input and output types have different sizes, but running a transmute between differently-sized types is UB.

Allowed only in MirPhase::Runtime; Earlier it’s a TerminatorKind::Call.
