Crate rustc_query_impl 

Support for serializing the dep-graph and reloading it.

Modules

_dep_kind_vtable_ctors 🔒

Module containing a named function for each dep kind (including queries) that creates a DepKindVTable.

plumbing 🔒

The implementation of the query system itself. This defines the macros that generate the actual methods on tcx which find and execute the provider, manage the caches, and so forth.

profiling_support 🔒

query_impl 🔒

Structs

QueryCtxt

Implements QueryContext for use by rustc_query_system, since that crate does not have direct access to [TyCtxt].

QueryFlags 🔒

SemiDynamicQueryDispatcher 🔒

Combines a [QueryVTable] with some additional compile-time booleans to implement QueryDispatcher, for use by code in rustc_query_system.

Constants

ALLOC_SELF_PROFILE_QUERY_STRINGS 🔒

ENCODE_QUERY_RESULTS 🔒

PER_QUERY_GATHER_ACTIVE_JOBS_FNS 🔒

Used by collect_active_jobs_from_all_queries to iterate over all queries, and gather the active jobs for each query.

QUERY_KEY_HASH_VERIFY 🔒

Traits

QueryDispatcherUnerased 🔒

Provides access to vtable-like operations for a query (by creating a QueryDispatcher), but also keeps track of the “unerased” value type of the query (i.e. the actual result type in the query declaration).

Functions

alloc_self_profile_query_strings

All self-profiling events generated by the query engine use virtual StringIds for their event_id. This method makes all those virtual StringIds point to actual strings.
