given for a query with key
self
, what span should we use?Source§fn key_as_def_id(&self) -> Option<DefId>

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.
