Struct terminus_store::store::Store

pub struct Store { /* fields omitted */ }

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

Implementations

impl Store

pub fn new<Labels: 'static + LabelStore, Layers: 'static + LayerStore>(
    label_store: Labels,
    layer_store: Layers
) -> Store

Create a new store from the given label and layer store

pub fn create(
    &self,
    label: &str
) -> impl Future<Item = NamedGraph, Error = Error> + Send

Create a new database with the given name

If the database already exists, this will return an error

pub fn open(
    &self,
    label: &str
) -> impl Future<Item = Option<NamedGraph>, Error = 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]
) -> impl Future<Item = Option<StoreLayer>, Error = Error>

pub fn create_base_layer(
    &self
) -> impl Future<Item = StoreLayerBuilder, Error = Error> + Send

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>

Trait Implementations

impl Clone for Store

fn clone(&self) -> Store

Returns a copy of the value.

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

Performs copy-assignment from source.
