Skip to main content Module query Copy item path Source pub use crate::queries::Providers ;arena_cached 🔒 caches 🔒 erase To improve compile times and code size for the compiler itself, query
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. into_query_key 🔒 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 🔒 Cycle 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 QueryJob Represents an active query job. QueryJobId A value uniquely identifying an active query job. QueryLatch QueryStackFrame Description of a frame in the query stack. QueryState For a particular query, keeps track of “active” keys, i.e. keys whose
evaluation has started but has not yet finished successfully. QuerySystem QueryVTable Stores data and metadata (e.g. function pointers) for a particular query. 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. TyCtxtAt TyCtxtEnsureDone TyCtxtEnsureOk TyCtxtEnsureResult 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. ActiveKeyStatus For a particular query and key, tracks the status of a query evaluation
that has started, but has not yet finished successfully. EnsureMode Distinguishes between tcx.ensure_ok() and tcx.ensure_done() in shared
code paths that handle both modes. QueryMode AsLocalQueryKey IntoQueryKey Argument-conversion trait used by some queries and other TyCtxt methods. QueryCache Trait for types that serve as an in-memory cache for query results,
for a given key (argument) type and value (return) type. QueryKey Controls what types can legally be used as the key for a query. describe_as_module
