Trait Implementations

impl Database for TestDb

fn sweep_all(&self, strategy: SweepStrategy)

Iterates through all query storage and removes any values that have not been used since the last revision was created. The intended use-cycle is that you first execute all of your “main” queries; this will ensure that all query values they consume are marked as used. You then invoke this method to remove other values that were not needed for your main query results.

fn salsa_event(&self, event_fn: Event)

This function is invoked at key points in the salsa runtime. It permits the database to be customized and to inject logging or other custom behavior.

fn on_propagated_panic(&self) -> !

This function is invoked when a dependent query is being computed by the other thread, and that thread panics.

fn salsa_runtime(&self) -> &Runtime

Gives access to the underlying salsa runtime.

fn salsa_runtime_mut(&mut self) -> &mut Runtime

Gives access to the underlying salsa runtime.

impl DatabaseOps for TestDb

fn ops_database(&self) -> &dyn Database

Upcast this type to a dyn Database.

fn ops_salsa_runtime(&self) -> &Runtime

Gives access to the underlying salsa runtime.

fn ops_salsa_runtime_mut(&mut self) -> &mut Runtime

Gives access to the underlying salsa runtime.

fn fmt_index(&self, input: DatabaseKeyIndex, fmt: &mut Formatter<'_>) -> Result

Formats a database key index in a human readable fashion.

fn maybe_changed_since( &self, input: DatabaseKeyIndex, revision: Revision, ) -> bool

True if the computed value for input may have changed since revision.

fn for_each_query(&self, op: &mut dyn FnMut(&dyn QueryStorageMassOps))

Executes the callback for each kind of query.

impl DatabaseStorageTypes for TestDb

type DatabaseStorage = __SalsaDatabaseStorage

Defines the “storage type”, where all the query data is kept. This type is defined by the database_storage macro.

impl Default for TestDb

fn default() -> TestDb

Returns the “default value” for a type.

impl HasQueryGroup<SourceDbStorage> for TestDb

fn group_storage(&self) -> &<SourceDbStorage as QueryGroup>::GroupStorage

Access the group storage struct from the database.
