pub type ProvidedValue<'tcx> = AssocItem;
Expand description
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.
Aliased Type§
struct ProvidedValue<'tcx> {
pub def_id: DefId,
pub name: Symbol,
pub kind: AssocKind,
pub container: AssocItemContainer,
pub trait_item_def_id: Option<DefId>,
pub fn_has_self_parameter: bool,
pub opt_rpitit_info: Option<ImplTraitInTraitData>,
pub is_effects_desugaring: bool,
}
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.
is_effects_desugaring: bool
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.
