Struct ConstOperand

pub struct ConstOperand<'tcx> {
    pub span: Span,
    pub user_ty: Option<UserTypeAnnotationIndex>,
    pub const_: Const<'tcx>,
}

Fields

span: Span

user_ty: Option<UserTypeAnnotationIndex>

Optional user-given type: for something like collect::<Vec<_>>, this would be present and would indicate that Vec<_> was explicitly specified.

Needed for NLL to impose user-given type constraints.

const_: Const<'tcx>

Implementations

impl<'tcx> ConstOperand<'tcx>

pub fn check_static_ptr(&self, tcx: TyCtxt<'_>) -> Option<DefId>

pub fn ty(&self) -> Ty<'tcx>

Trait Implementations

impl<'tcx> Clone for ConstOperand<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for ConstOperand<'tcx>

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

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<__D> for ConstOperand<'tcx>

fn decode(__decoder: &mut __D) -> Self

impl<'tcx> Display for ConstOperand<'tcx>

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

Formats the value using the given formatter.

impl<'tcx, __E: TyEncoder<I = TyCtxt<'tcx>>> Encodable<__E> for ConstOperand<'tcx>

fn encode(&self, __encoder: &mut __E)

impl<'tcx> Hash for ConstOperand<'tcx>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for ConstOperand<'tcx>

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher, )

impl<'tcx> PartialEq for ConstOperand<'tcx>

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl<'tcx> TypeFoldable<TyCtxt<'tcx>> for ConstOperand<'tcx>

fn try_fold_with<__F: FallibleTypeFolder<TyCtxt<'tcx>>>( self, __folder: &mut __F, ) -> Result<Self, __F::Error>

The entry point for folding. To fold a value t with a folder f call: t.try_fold_with(f).

fn fold_with<F>(self, folder: &mut F) -> Self

where F: TypeFolder<I>,

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.

impl<'tcx> TypeVisitable<TyCtxt<'tcx>> for ConstOperand<'tcx>

fn visit_with<__V: TypeVisitor<TyCtxt<'tcx>>>( &self, __visitor: &mut __V, ) -> __V::Result

The entry point for visiting. To visit a value t with a visitor v call: t.visit_with(v).

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.
