Struct RootDatabase 

pub struct RootDatabase { /* private fields */ }

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 salsa_runtime_mut(&mut self) -> &mut Runtime

Gives access to the underlying salsa runtime.

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 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 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 HasQueryGroup<RirDatabaseStorage> for RootDatabase

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

Access the group storage struct from the database.

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.
