Struct terminus_store::layer::ChildLayerFileBuilderPhase2

pub struct ChildLayerFileBuilderPhase2<F: 'static + FileLoad + FileStore + Clone + Send + Sync> { /* fields omitted */ }

Second phase of child layer building.

This builder takes ordered triple additions and removals. When all data has been added, finalize() will build a layer.

Implementations

impl<F: 'static + FileLoad + FileStore + Clone + Send + Sync> ChildLayerFileBuilderPhase2<F>

pub fn add_triple(
    self,
    subject: u64,
    predicate: u64,
    object: u64
) -> Box<dyn Future<Item = Self, Error = Error> + Send>

Add the given subject, predicate and object.

This will panic if a greater triple has already been added, and do nothing if the triple is already part of the parent.

pub fn remove_triple(
    self,
    subject: u64,
    predicate: u64,
    object: u64
) -> Box<dyn Future<Item = Self, Error = Error> + Send>

Remove the given subject, predicate and object.

This will panic if a greater triple has already been removed, and do nothing if the parent doesn't know aobut this triple.

pub fn add_id_triples<I: 'static + IntoIterator<Item = IdTriple>>(
    self,
    triples: I
) -> impl Future<Item = Self, Error = Error>

Add the given triple.

This will panic if a greater triple has already been added, and do nothing if the parent already contains this triple.

pub fn remove_id_triples<I: 'static + IntoIterator<Item = IdTriple>>(
    self,
    triples: I
) -> impl Future<Item = Self, Error = Error>

Remove the given triple.

This will panic if a greater triple has already been removed, and do nothing if the parent doesn't know aobut this triple.

pub fn finalize(self) -> impl Future<Item = (), Error = Error>

Write the layer data to storage.
