Federation executor for executing SERVICE clauses

Implementations§

Source§

impl FederationExecutor

Source

pub fn new() -> Result<Self, OxirsError>

Create a new federation executor

Source

pub async fn execute_service( &self, endpoint: &NamedNodePattern, pattern: &GraphPattern, silent: bool, bindings: &[HashMap<String, Term>], ) -> Result<Vec<HashMap<String, Term>>, OxirsError>

Execute a SERVICE clause

§Arguments
  • endpoint - The SERVICE endpoint (IRI or variable)
  • pattern - The graph pattern to execute at the endpoint
  • silent - If true, suppress errors and return empty results
  • bindings - Current variable bindings from local query
§Returns

Vector of solution bindings from the remote endpoint

Source

pub fn merge_bindings( &self, local: Vec<HashMap<String, Term>>, remote: Vec<HashMap<String, Term>>, ) -> Vec<HashMap<String, Term>>

Merge local and remote bindings
