fn prepare_for_eval( self, tcx: TyCtxt<'tcx>, param_env: ParamEnv<'tcx>, ) -> (ParamEnv<'tcx>, Self)

FIXME(RalfJung): I cannot explain what this does or why it makes sense, but not doing this hurts performance.

impl<I> Clone for UnevaluatedConst<I>

where I: Interner,

fn clone(&self) -> UnevaluatedConst<I>

Returns a copy of the value.

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

Performs copy-assignment from source.

where I: Interner, __E: TyEncoder<I = I>, <I as Interner>::DefId: Encodable<__E>, <I as Interner>::GenericArgs: Encodable<__E>,

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

impl<I> Hash for UnevaluatedConst<I>

where I: Interner,

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

where __H: Hasher,

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

fn hash_stable( &self, __hcx: &mut __CTX, __hasher: &mut StableHasher<SipHasher128>, )

impl<I> IntoDiagArg for UnevaluatedConst<I>

where I: Interner,

fn into_diag_arg(self) -> DiagArgValue

impl<I, J> Lift<J> for UnevaluatedConst<I>

where I: Interner, J: Interner, <I as Interner>::DefId: Lift<J, Lifted = <J as Interner>::DefId>, <I as Interner>::GenericArgs: Lift<J, Lifted = <J as Interner>::GenericArgs>,

type Lifted = UnevaluatedConst<J>

fn lift_to_interner(self, interner: J) -> Option<UnevaluatedConst<J>>

impl<I> PartialEq for UnevaluatedConst<I>

where I: Interner,

fn eq(&self, __other: &UnevaluatedConst<I>) -> 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.

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.
