Expand description

This type contains all the things within InferCtxt that sit within a RefCell and are involved with taking/rolling back snapshots. Snapshot operations are hot enough that we want only one call to borrow_mut per call to start_snapshot and rollback_to.

Fields§

§projection_cache: ProjectionCacheStorage<'tcx>

Cache for projections. This cache is snapshotted along with the infcx.

Public so that traits::project can use it.

Caches for opaque type inference.

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.
