Type Alias TraitRef 

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

Aliased Type

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

Fields

def_id: DefId

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

Trait Implementations

impl<'tcx> Erasable for TraitRef<'tcx>

type Storage = [u8; 16]

Storage type to used for erased values of this type. Should be [u8; N], where N is equal to size_of::<Self>.

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

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?

type Cache<V> = DefaultCache<Self, V>

The type of in-memory cache to use for queries with this key type.

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

fn print(&self, p: &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.
