pub struct InferCtxtInner<'db> { /* private fields */ }
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
.
