Module rustc_query_system::query

Modules

• caches 🔒
• config 🔒
  Query configuration and description traits.
• job 🔒
• 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.

Structs

• DefaultCacheSelector
• QueryInfo
  Represents a span and a query key.
• QueryJob
  Represents an active query job.
• QueryJobId
  A value uniquely identifying an active query job.
• QueryJobInfo
• QuerySideEffects
  Tracks ‘side effects’ for a particular query. This struct is saved to disk along with the query result, and loaded from disk if we mark the query as green. This allows us to ‘replay’ changes to global state that would otherwise only occur if we actually executed the query method.
• QueryStackFrame
  Description of a frame in the query stack.
• QueryState
• SingleCacheSelector
• VecCacheSelector

Enums

• QueryMode

Traits

• CacheSelector
• QueryCache
• QueryConfig
• QueryContext

Functions

• force_query
• get_query_incr
• get_query_non_incr
• print_query_stack
• try_get_cached
  Checks if the query is already computed and in the cache. It returns the shard index and a lock guard to the shard, which will be used if the query is not in the cache and we need to compute it.

Type Aliases

• HashResult
• QueryMap
