Struct Storage 

pub struct Storage<Db> { /* private fields */ }

Concrete implementation of the Database trait with local state that can be used to drive computations.

Implementations

impl<Db: Database> Storage<Db>

pub fn new( event_callback: Option<Box<dyn Fn(Event) + Send + Sync + 'static>>, ) -> Self

Create a new database storage.

The event_callback function is invoked by the salsa runtime at various points during execution.

pub fn builder() -> StorageBuilder<Db>

Returns a builder for database storage.

pub fn into_zalsa_handle(self) -> StorageHandle<Db>

Convert this instance of Storage into a StorageHandle.

This will discard the local state of this Storage, thereby returning a value that is both Sync and std::panic::UnwindSafe.

Trait Implementations

impl<Db: Database> Clone for Storage<Db>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Db: Database> Default for Storage<Db>

fn default() -> Self

Returns the “default value” for a type.

impl<Db> Drop for Storage<Db>

fn drop(&mut self)

Executes the destructor for this type.
