[][src]Struct terminus_store::store::NamedGraph

pub struct NamedGraph { /* fields omitted */ }

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 NamedGraph[src]

pub fn name(&self) -> &str[src]

pub fn head(
    &self
) -> impl Future<Item = Option<StoreLayer>, Error = Error> + Send
[src]

Returns the layer this database points at

pub fn set_head(
    &self,
    layer: &StoreLayer
) -> impl Future<Item = bool, Error = Error> + Send
[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: &StoreLayer
) -> impl Future<Item = bool, Error = Error> + Send
[src]

Set the database label to the given layer if it is a valid ancestor, returning false otherwise
