}
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.

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.
