Modules
Debugging APIs: these are meant for use when unit-testing or
debugging your application but aren’t ordinarily needed.
Macros
This macro generates the “query storage” that goes into your query
context.
A macro that helps in defining the “context trait” of a given
module. This is a trait that defines everything that a block of
queries need to execute, as well as defining the queries
themselves that are exported for others to use.
Structs
The guard returned by
lock_revision. Once this guard is dropped,
the revision will be unlocked, and calls to set can proceed.The salsa runtime stores the storage for all queries as well as
tracking the query stack and dependencies between cycles.
The sweep strategy controls what data we will keep/discard when we
do a GC-sweep. The default (
SweepStrategy::default) is to keep
all memoized values used in the current revision.Traits
The base trait which your “query context” must implement. Gives
access to the salsa runtime, which you must embed into your query
context (along with whatever other state you may require).
Indicates a database that also supports parallel query
evaluation. All of Salsa’s base query support is capable of
parallel execution, but for it to work, your query key/value types
must also be
Send, as must any additional data in your database.
