Type Alias TraitRef

pub type TraitRef<'tcx> = TraitRef<TyCtxt<'tcx>>;

Aliased Type

struct TraitRef<'tcx> {
    pub def_id: DefId,
    pub args: &'tcx RawList<(), GenericArg<'tcx>>,
    /* private fields */
}

Fields

args: &'tcx RawList<(), GenericArg<'tcx>>

Trait Implementations

impl<'tcx> EraseType for TraitRef<'tcx>

type Result = [u8; 16]

impl<'tcx> Key for TraitRef<'tcx>

type Cache<V> = DefaultCache<TraitRef<TyCtxt<'tcx>>, V>

fn default_span(&self, tcx: 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 def_id_for_ty_in_cycle(&self) -> Option<DefId>

Used to detect when ADT def ids are used as keys in a cycle for better error reporting.

impl ParameterizedOverTcx for TraitRef<'static>

type Value<'tcx> = TraitRef<TyCtxt<'tcx>>

impl<'tcx, P: PrettyPrinter<'tcx>> Print<'tcx, P> for TraitRef<'tcx>

fn print(&self, cx: &mut P) -> Result<(), PrintError>

impl<'tcx> PrintTraitRefExt<'tcx> for TraitRef<'tcx>

fn print_only_trait_path(self) -> TraitRefPrintOnlyTraitPath<'tcx>

fn print_trait_sugared(self) -> TraitRefPrintSugared<'tcx>

fn print_only_trait_name(self) -> TraitRefPrintOnlyTraitName<'tcx>

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.
