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>>

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.
