[−][src]Struct rustc_infer::traits::ObligationCause
The reason why we incurred this obligation; used for error reporting.
As the happy path does not care about this struct, storing this on the heap ends up increasing performance.
We do not want to intern this as there are a lot of obligation causes which only live for a short period of time.
Fields
data: Option<Rc<ObligationCauseData<'tcx>>>None for ObligationCause::dummy, Some otherwise.
