Struct rustc_trait_selection::solve::fulfill::ObligationStorage
source · struct ObligationStorage<'tcx> {
overflowed: Vec<PredicateObligation<'tcx>>,
pending: Vec<PredicateObligation<'tcx>>,
}
Fields§
§overflowed: Vec<PredicateObligation<'tcx>>
Obligations which resulted in an overflow in fulfillment itself.
We cannot eagerly return these as error so we instead store them here
to avoid recomputing them each time select_where_possible
is called.
This also allows us to return the correct FulfillmentError
for them.
pending: Vec<PredicateObligation<'tcx>>

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