Struct terminus_store::store::sync::SyncStore

pub struct SyncStore { /* fields omitted */ }

A store, storing a set of layers and database labels pointing to these layers

Implementations

impl SyncStore

pub fn wrap(inner: Store) -> Self

wrap an asynchronous Store, running all futures on a lazily-constructed tokio runtime

The runtime will be constructed on the first call to wrap. Any subsequent SyncStore will reuse the same runtime.

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

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

pub fn get_layer_from_id(
    &self,
    layer: [u32; 5]
) -> Result<Option<SyncStoreLayer>, 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 export_layers(
    &self,
    layer_ids: Box<dyn Iterator<Item = [u32; 5]>>
) -> Vec<u8>

pub fn import_layers(
    &self,
    pack: &[u8],
    layer_ids: Box<dyn Iterator<Item = [u32; 5]>>
) -> Result<(), Error>
