Variants

Int(IntTy)

Various types that are represented as ints and handled mostly in the same way, merged for easier matching.

Float

Floating-point types.

FnPtr

Function pointers.

Ptr(TypeAndMut<'tcx>)

Raw pointers.

DynStar

Casting into a dyn* value.

Implementations

impl<'tcx> CastTy<'tcx>

pub fn from_ty(t: Ty<'tcx>) -> Option<CastTy<'tcx>>

Returns Some for integral/pointer casts. Casts like unsizing casts will return None.

Trait Implementations

impl<'tcx> Clone for CastTy<'tcx>

fn clone(&self) -> CastTy<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for CastTy<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx> PartialEq<CastTy<'tcx>> for CastTy<'tcx>

fn eq(&self, other: &CastTy<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'tcx> Copy for CastTy<'tcx>

impl<'tcx> Eq for CastTy<'tcx>

impl<'tcx> StructuralEq for CastTy<'tcx>

impl<'tcx> StructuralPartialEq for CastTy<'tcx>

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.
