See simplify_type

Note that we keep this type generic over the type of identifier it uses because we sometimes need to use SimplifiedTypeGen values as stable sorting keys (in which case we use a DefPathHash as id-type) but in the general case the non-stable but fast to construct DefId-version is the better choice.

Trait Implementations

impl<D> Clone for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq + Clone,

fn clone(&self) -> SimplifiedTypeGen<D>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<D> Debug for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq + Debug,

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

Formats the value using the given formatter.

impl<'tcx, D, __D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<__D> for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq + Decodable<__D>,

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

impl<'tcx, D, __E: TyEncoder<I = TyCtxt<'tcx>>> Encodable<__E> for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq + Encodable<__E>,

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

impl<D> Hash for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq + Hash,

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<'__ctx, D> HashStable<StableHashingContext<'__ctx>> for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq + HashStable<StableHashingContext<'__ctx>>,

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

impl ParameterizedOverTcx for SimplifiedTypeGen<DefId>

type Value<'tcx> = SimplifiedTypeGen<DefId>

impl<D> PartialEq<SimplifiedTypeGen<D>> for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq + PartialEq,

fn eq(&self, other: &SimplifiedTypeGen<D>) -> 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<D> Copy for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq + Copy,

impl<D> Eq for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq + Eq,

impl<D> StructuralEq for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq,

impl<D> StructuralPartialEq for SimplifiedTypeGen<D>where
    D: Copy + Debug + Eq,

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
