Trait Implementations

impl Database for RootDatabase

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 unwind_if_cancelled(&self)

Starts unwinding the stack if the current revision is cancelled.

fn salsa_runtime(&self) -> &Runtime

Gives access to the underlying salsa runtime.

fn synthetic_write(&mut self, durability: Durability)

A “synthetic write” causes the system to act as though some input of durability durability has changed. This is mostly useful for profiling scenarios.

impl DatabaseOps for RootDatabase

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 synthetic_write(&mut self, durability: Durability)

A “synthetic write” causes the system to act as though some input of durability durability has changed. This is mostly useful for profiling scenarios.

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

Formats a database key index in a human readable fashion.

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

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

fn cycle_recovery_strategy( &self, input: DatabaseKeyIndex, ) -> CycleRecoveryStrategy

Find the CycleRecoveryStrategy for a given input.

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

Executes the callback for each kind of query.

impl DatabaseStorageTypes for RootDatabase

type DatabaseStorage = __SalsaDatabaseStorage

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

impl Debug for RootDatabase

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

Formats the value using the given formatter.

impl Default for RootDatabase

fn default() -> RootDatabase

Returns the “default value” for a type.

impl Drop for RootDatabase

fn drop(&mut self)

Executes the destructor for this type.

impl FileLoader for RootDatabase

fn resolve_path(&self, path: AnchoredPath<'_>) -> Option<FileId>

fn relevant_crates(&self, file_id: FileId) -> Arc<[CrateId]>

Crates whose root’s source root is the same as the source root of file_id

impl HasQueryGroup<DefDatabaseStorage> for RootDatabase

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

Access the group storage struct from the database.

fn group_storage_mut( &mut self, ) -> (&<DefDatabaseStorage as QueryGroup>::GroupStorage, &mut Runtime)

Access the group storage struct from the database. Also returns a ref to the Runtime, since otherwise the database is borrowed and one cannot get access to it.

impl HasQueryGroup<ExpandDatabaseStorage> for RootDatabase

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

Access the group storage struct from the database.

fn group_storage_mut( &mut self, ) -> (&<ExpandDatabaseStorage as QueryGroup>::GroupStorage, &mut Runtime)

Access the group storage struct from the database. Also returns a ref to the Runtime, since otherwise the database is borrowed and one cannot get access to it.

impl HasQueryGroup<HirDatabaseStorage> for RootDatabase

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

Access the group storage struct from the database.

fn group_storage_mut( &mut self, ) -> (&<HirDatabaseStorage as QueryGroup>::GroupStorage, &mut Runtime)

Access the group storage struct from the database. Also returns a ref to the Runtime, since otherwise the database is borrowed and one cannot get access to it.

impl HasQueryGroup<InternDatabaseStorage> for RootDatabase

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

Access the group storage struct from the database.

fn group_storage_mut( &mut self, ) -> (&<InternDatabaseStorage as QueryGroup>::GroupStorage, &mut Runtime)

Access the group storage struct from the database. Also returns a ref to the Runtime, since otherwise the database is borrowed and one cannot get access to it.

impl HasQueryGroup<LineIndexDatabaseStorage> for RootDatabase

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

Access the group storage struct from the database.

fn group_storage_mut( &mut self, ) -> (&<LineIndexDatabaseStorage as QueryGroup>::GroupStorage, &mut Runtime)

Access the group storage struct from the database. Also returns a ref to the Runtime, since otherwise the database is borrowed and one cannot get access to it.

Access the group storage struct from the database.

fn group_storage_mut( &mut self, ) -> (&<SourceRootDatabaseStorage as QueryGroup>::GroupStorage, &mut Runtime)

Access the group storage struct from the database. Also returns a ref to the Runtime, since otherwise the database is borrowed and one cannot get access to it.

impl ParallelDatabase for RootDatabase

fn snapshot(&self) -> Snapshot<RootDatabase>

Creates a second handle to the database that holds the database fixed at a particular revision. So long as this “frozen” handle exists, any attempt to set an input will block.
