Struct Storage

pub struct Storage<DB: DatabaseStorageTypes> { /* private fields */ }

Stores the cached results and dependency information for all the queries defined on your salsa database. Also embeds a Runtime which is used to manage query execution. Every database must include a storage: Storage<Self> field.

Implementations

impl<DB: DatabaseStorageTypes> Storage<DB>

pub fn salsa_runtime(&self) -> &Runtime

Gives access to the underlying salsa runtime.

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

Gives access to the underlying salsa runtime.

pub fn query_store(&self) -> &DB::DatabaseStorage

Access the query storage tables. Not meant to be used directly by end users.

pub fn query_store_mut(&mut self) -> (&DB::DatabaseStorage, &mut Runtime)

Access the query storage tables. Not meant to be used directly by end users.

pub fn snapshot(&self) -> Self

Returns a “snapshotted” storage, suitable for use in a forked database. This snapshot hold a read-lock on the global state, which means that any attempt to set an input will block until the forked runtime is dropped. See ParallelDatabase::snapshot for more information.

Warning. This second handle is intended to be used from a separate thread. Using two database handles from the same thread can lead to deadlock.

Trait Implementations

impl<DB: DatabaseStorageTypes> Default for Storage<DB>

fn default() -> Self

Returns the “default value” for a type.
