Struct rustc_middle::traits::solve::cache::CacheEntry
source · struct CacheEntry<'tcx> {
success: Option<Success<'tcx>>,
cycle_participants: FxHashSet<CanonicalInput<'tcx>>,
with_overflow: FxHashMap<usize, WithDepNode<QueryResult<'tcx>>>,
}Expand description
The cache entry for a goal CanonicalInput.
This contains results whose computation never hit the
recursion limit in success, and all results which hit
the recursion limit in with_overflow.
Fields§
§success: Option<Success<'tcx>>§cycle_participants: FxHashSet<CanonicalInput<'tcx>>We have to be careful when caching roots of cycles.
See the doc comment of StackEntry::cycle_participants for more
details.

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.
