Implementations

impl SimplifiedType

pub fn def(self) -> Option<DefId>

Trait Implementations

impl Clone for SimplifiedType

fn clone(&self) -> SimplifiedType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SimplifiedType

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

Formats the value using the given formatter.

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

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

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

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

impl EraseType for SimplifiedType

type Result = [u8; 16]

impl Hash for SimplifiedType

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> HashStable<StableHashingContext<'__ctx>> for SimplifiedType

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

impl Key for SimplifiedType

type CacheSelector = DefaultCacheSelector<SimplifiedType>

fn default_span(&self, _: TyCtxt<'_>) -> Span

In the event that a cycle occurs, if no explicit span has been given for a query with key self, what span should we use?

fn key_as_def_id(&self) -> Option<DefId>

If the key is a DefId or DefId–equivalent, return that DefId. Otherwise, return None.

fn ty_adt_id(&self) -> Option<DefId>

impl ParameterizedOverTcx for SimplifiedType

type Value<'tcx> = SimplifiedType

impl PartialEq<SimplifiedType> for SimplifiedType

fn eq(&self, other: &SimplifiedType) -> 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<'a> ToStableHashKey<StableHashingContext<'a>> for SimplifiedType

type KeyType = Fingerprint

fn to_stable_hash_key(&self, hcx: &StableHashingContext<'a>) -> Fingerprint

impl Copy for SimplifiedType

impl Eq for SimplifiedType

impl StructuralEq for SimplifiedType

impl StructuralPartialEq for SimplifiedType

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.
