pub struct PreparedSparqlUpdate {
    evaluator: QueryEvaluator,
    update: Update,
    using_datasets: Vec<Option<QueryDatasetSpecification>>,
}

Available on crate feature rdf only.

A prepared SPARQL update.

Usage example:

use oxigraph::sparql::SparqlEvaluator;
use oxigraph::store::Store;

let prepared_update = SparqlEvaluator::new().parse_update(
    "INSERT DATA { <http://example.com> <http://example.com> <http://example.com> }",
)?;
prepared_update.on_store(&Store::new()?).execute()?;

Fields

evaluator: QueryEvaluator

update: Update

using_datasets: Vec<Option<QueryDatasetSpecification>>

Implementations

impl PreparedSparqlUpdate

pub fn using_datasets(&self) -> impl Iterator<Item = &QueryDatasetSpecification>

Returns the query dataset specification in DELETE/INSERT operations.

pub fn using_datasets_mut( &mut self, ) -> impl Iterator<Item = &mut QueryDatasetSpecification>

Returns the query dataset specification in DELETE/INSERT operations.

pub fn on_store(self, store: &Store) -> BoundPreparedSparqlUpdate<'_, '_>

Bind the prepared update to the [Store] it should be evaluated on.

Usage example:

use oxigraph::sparql::SparqlEvaluator;
use oxigraph::store::Store;

let prepared_update = SparqlEvaluator::new().parse_update(
    "INSERT DATA { <http://example.com> <http://example.com> <http://example.com> }",
)?;
prepared_update.on_store(&Store::new()?).execute()?;

pub fn on_transaction<'a, 'b>( self, transaction: &'a mut Transaction<'b>, ) -> BoundPreparedSparqlUpdate<'a, 'b>

where 'b: 'a,

Bind the prepared update to the [Transaction] it should be evaluated on.

Usage example:

use oxigraph::sparql::SparqlEvaluator;
use oxigraph::store::Store;

let prepared_update = SparqlEvaluator::new().parse_update(
    "INSERT DATA { <http://example.com> <http://example.com> <http://example.com> }",
)?;
let store = Store::new()?;
let mut transaction = store.start_transaction()?;
prepared_update.on_transaction(&mut transaction).execute()?;

Trait Implementations

impl Clone for PreparedSparqlUpdate

fn clone(&self) -> PreparedSparqlUpdate

Returns a duplicate of the value.

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