source · pub struct SyncStore { /* private fields */ }
Expand description
A store, storing a set of layers and database labels pointing to these layers.
Implementations§
source§impl SyncStore
impl SyncStore
sourcepub fn wrap(inner: Store) -> Self
pub fn wrap(inner: Store) -> Self
wrap an asynchronous Store
, running all futures on a lazily-constructed tokio runtime.
sourcepub fn create(&self, label: &str) -> Result<SyncNamedGraph, Error>
pub fn create(&self, label: &str) -> Result<SyncNamedGraph, Error>
Create a new database with the given name.
If the database already exists, this will return an error.
sourcepub fn open(&self, label: &str) -> Result<Option<SyncNamedGraph>, Error>
pub fn open(&self, label: &str) -> Result<Option<SyncNamedGraph>, Error>
Open an existing database with the given name, or None if it does not exist.
sourcepub fn delete(&self, label: &str) -> Result<bool>
pub fn delete(&self, label: &str) -> Result<bool>
Delete an existing database with the given name. Returns true if this database was deleted and false otherwise.
sourcepub fn labels(&self) -> Result<Vec<String>, Error>
pub fn labels(&self) -> Result<Vec<String>, Error>
Return list of names of all existing databases.
sourcepub fn get_layer_from_id(
&self,
layer: [u32; 5]
) -> Result<Option<SyncStoreLayer>, Error>
pub fn get_layer_from_id( &self, layer: [u32; 5] ) -> Result<Option<SyncStoreLayer>, Error>
Retrieve a layer with the given name from the layer store this Store was initialized with.
sourcepub fn create_base_layer(&self) -> Result<SyncStoreLayerBuilder, Error>
pub fn create_base_layer(&self) -> Result<SyncStoreLayerBuilder, Error>
Create a base layer builder, unattached to any database label.
After having committed it, use set_head
on a NamedGraph
to attach it.
pub fn merge_base_layers( &self, layers: &[[u32; 5]], temp_dir: &Path ) -> Result<[u32; 5], Error>
sourcepub fn export_layers(
&self,
layer_ids: Box<dyn Iterator<Item = [u32; 5]> + Send>
) -> Result<Vec<u8>>
pub fn export_layers( &self, layer_ids: Box<dyn Iterator<Item = [u32; 5]> + Send> ) -> Result<Vec<u8>>
Export the given layers by creating a pack, a Vecimport_layers
on a different store.
sourcepub fn import_layers(
&self,
pack: &[u8],
layer_ids: Box<dyn Iterator<Item = [u32; 5]> + Send>
) -> Result<()>
pub fn import_layers( &self, pack: &[u8], layer_ids: Box<dyn Iterator<Item = [u32; 5]> + Send> ) -> Result<()>
Import the specified layers from the given pack, a byte slice that was previously generated with export_layers
, on another store, and possibly even another machine).
After this operation, the specified layers will be retrievable from this store, provided they existed in the pack. specified layers that are not in the pack are silently ignored.
