Struct keeshond_datapack::DataMultistore

pub struct DataMultistore { /* private fields */ }

Storage that allows lookup and access of DataObjects of multiple types by wrapping multiple DataStores.

Implementations

impl DataMultistore

pub fn new(source_manager: Rc<RefCell<SourceManager>>) -> DataMultistore

Constructs a new DataMultistore that gets its Sources from the given SourceManager

pub fn register_type<D: DataObject + 'static>(&self) -> bool

Informs the DataMultistore of a new DataObject to manage a DataStore for. Returns true if successful.

pub fn lock(&mut self, locked: bool)

Sets whether mutable access to types is disallowed.

pub fn store<D: DataObject + 'static>(&self) -> Ref<'_, DataStore<D>>

Returns a reference to the DataStore of the given type. Panics if it cannot be retrieved.

pub fn store_mut<D: DataObject + 'static>(&self) -> RefMut<'_, DataStore<D>>

Returns a mutable reference to the DataStore of the given type. Panics if it cannot be retrieved.

pub fn try_store<D: DataObject + 'static>(
    &self
) -> Option<Ref<'_, DataStore<D>>>

Returns a reference to the DataStore of the given type. Returns None if it cannot be retrieved.

pub fn try_store_mut<D: DataObject + 'static>(
    &self
) -> Option<RefMut<'_, DataStore<D>>>

Returns a mutable reference to the DataStore of the given type. Returns None if it cannot be retrieved.

pub fn unload_all(&self)

Unloads all packages from memory. Any DataObjects will be dropped, but pathname-id mappings will be retained in memory so that existing references will not be invalidated. Returns true if the package was loaded.

pub fn unload_unused(&self)

Unloads all packages that do not have an active PackageUseToken.

pub fn package_source_id(&self, package_name: &str) -> SourceId

Returns the SourceId of the Source that has the given package, going in reverse order of when they were added. If no suitable Source is available, returns a “null” ID.
