[−][src]Struct terminus_store::store::sync::SyncNamedGraph
A named graph in terminus-store.
Named graphs in terminus-store are basically just a label pointing to a layer. Opening a read transaction to a named graph is just getting hold of the layer it points at, as layers are read-only. Writing to a named graph is just making it point to a new layer.
Implementations
impl SyncNamedGraph[src]
pub fn name(&self) -> &str[src]
pub fn head(&self) -> Result<Option<SyncStoreLayer>, Error>[src]
Returns the layer this database points at
pub fn set_head(&self, layer: &SyncStoreLayer) -> Result<bool, Error>[src]
Set the database label to the given layer if it is a valid ancestor, returning false otherwise
pub fn force_set_head(&self, layer: &SyncStoreLayer) -> Result<bool, Error>[src]
