Fields§
§item: AssocItem
§kind: PickKind<'tcx>
§import_ids: SmallVec<[LocalDefId; 1]>
§autoderefs: usize
Indicates that the source expression should be autoderef’d N times
A = expr | *expr | **expr | ...
autoref_or_ptr_adjustment: Option<AutorefOrPtrAdjustment>
Indicates that we want to add an autoref (and maybe also unsize it), or if the receiver is
*mut T
, convert it to *const T
.
self_ty: Ty<'tcx>
§unstable_candidates: Vec<(Candidate<'tcx>, Symbol)>
Unstable candidates alongside the stable ones.
Implementations§

impl<'tcx> Pick<'tcx>
sourcepub fn differs_from(&self, other: &Self) -> bool
pub fn differs_from(&self, other: &Self) -> bool
In case there were unstable name collisions, emit them as a lint.
Checks whether two picks do not refer to the same trait item for the same Self
type.
Only useful for comparisons of picks in order to improve diagnostics.
Do not use for type checking.

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.
