values are “erased” in some contexts (e.g. inside in-memory cache types),
to reduce the number of generic instantiations created during codegen. inner 🔒 Helper functions that serve as the immediate implementation of
tcx.$query(..) and its variations. job 🔒 keys 🔒 Defines the set of legal keys that can be used in queries. modifiers 🔒 This contains documentation which is linked from query modifiers used in the rustc_queries! proc macro. on_disk_cache plumbing stack 🔒 DefIdCache In-memory cache for queries whose key is a DefId DefaultCache In-memory cache for queries whose keys aren’t suitable for any of the
more specialized kinds of cache. Backed by a sharded hashmap. LocalCrate Placeholder for CrateNum’s “local” counterpart QueryInfo Represents a span and a query key. QueryJob Represents an active query job. QueryJobId A value uniquely identifying an active query job. QueryLatch QueryStackDeferred Track a ‘side effect’ for a particular query.
This is used to hold a closure which can create QueryStackFrameExtra. QueryStackFrame Description of a frame in the query stack. QueryStackFrameExtra QueryWaiter SingleCache In-memory cache for queries whose key type only has one value (e.g. ()).
The cache therefore only needs to store one query return value. VecCache In-memory cache for queries whose keys are densely-numbered IDs
(e.g CrateNum, LocalDefId), and can therefore be used as indices
into a dense vector of cached values. AsLocalKey Key The Key trait controls what types can legally be used as the key
for a query. QueryCache Trait for types that serve as an in-memory cache for query results,
for a given key (argument) type and value (return) type. QueryContext describe_as_module QueryCacheKey Traits that all query keys must satisfy.
