Type Alias rustc_middle::query::queries::specialization_graph_of::ProvidedValue

pub type ProvidedValue<'tcx> = Graph;

This type alias specifies the type returned from query providers and the type used for decoding. For regular queries this is the declared returned type V, but arena_cache will use <V as Deref>::Target instead.

Implementations

impl Graph

pub fn new() -> Graph

pub fn parent(&self, child: DefId) -> DefId

The parent of a given impl, which is the DefId of the trait when the impl is a “specialization root”.

Trait Implementations

impl Debug for Graph

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

Formats the value using the given formatter.

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

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

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

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

impl<'__ctx> HashStable<StableHashingContext<'__ctx>> for Graph

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

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.
