Expand description
References to traits in impls.
resolve
maps each TraitRef
’s ref_id
to its defining trait; that’s all
that the ref_id
is for. Note that ref_id
’s value is not the HirId
of the
trait being referred to but just a unique HirId
that serves as a key
within the resolution map.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
