Struct rustc_middle::ty::assoc::AssocItem

pub struct AssocItem {
    pub def_id: DefId,
    pub name: Symbol,
    pub kind: AssocKind,
    pub container: AssocItemContainer,

Information about an associated item

Fields

def_id: DefId

name: Symbol

kind: AssocKind

container: AssocItemContainer

trait_item_def_id: Option<DefId>

If this is an item in an impl of a trait then this is the DefId of the associated item on the trait that this implements.

fn_has_self_parameter: bool

Whether this is a method with an explicit self as its first parameter, allowing method calls.

opt_rpitit_info: Option<ImplTraitInTraitData>

Some if the associated item (an associated type) comes from the return-position impl Trait in trait desugaring. The ImplTraitInTraitData provides additional information about its source.

Implementations

impl AssocItem

pub fn ident(&self, tcx: TyCtxt<'_>) -> Ident

pub fn defaultness(&self, tcx: TyCtxt<'_>) -> Defaultness

Gets the defaultness of the associated item. To get the default associated type, use the type_of query on the DefId of the type.

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

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

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

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

pub fn signature(&self, tcx: TyCtxt<'_>) -> String

pub fn is_impl_trait_in_trait(&self) -> bool

Trait Implementations

impl Clone for AssocItem

fn clone(&self) -> AssocItem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AssocItem

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for AssocItem

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

impl<__E: Encoder> Encodable<__E> for AssocItem

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

impl EraseType for AssocItem

type Result = [u8; 40]

impl Hash for AssocItem

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 AssocItem

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

impl PartialEq<AssocItem> for AssocItem

fn eq(&self, other: &AssocItem) -> 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<'tcx> TypeFoldable<TyCtxt<'tcx>> for AssocItem

fn try_fold_with<F: FallibleTypeFolder<TyCtxt<'tcx>>>( self, _: &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: TypeFolder<TyCtxt<'tcx>>>(self, _: &mut F) -> Self

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 AssocItem

fn visit_with<F: TypeVisitor<TyCtxt<'tcx>>>( &self, _: &mut F ) -> ControlFlow<F::BreakTy>

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

impl Copy for AssocItem

impl Eq for AssocItem

impl StructuralEq for AssocItem

impl StructuralPartialEq for AssocItem

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.
