Struct reasonable::reasoner::Reasoner

pub struct Reasoner { /* fields omitted */ }

Reasoner is the interface to the reasoning engine. Instances of Reasoner maintain the state required to do reasoning.

use reasonable::reasoner::Reasoner;
let mut r = Reasoner::new();
// load in an ontology file
r.load_file("example_models/ontologies/Brick.n3").unwrap();
// load in another ontology file
r.load_file("example_models/ontologies/rdfs.ttl").unwrap();
// load in more triples
r.load_file("example_models/small1.n3").unwrap();
// perform reasoning
r.reason();
// dump to file
r.dump_file("output.ttl").unwrap();

Implementations

impl Reasoner

pub fn new() -> Self

Create a new Reasoner instance

pub fn load_triples_str(
    &mut self,
    triples: Vec<(&'static str, &'static str, &'static str)>
)

Load in a vector of triples

pub fn load_triples(&mut self, triples: Vec<(Node, Node, Node)>)

Load in a vector of triples

pub fn dump_file(&mut self, filename: &str) -> Result<(), Error>

Dump the contents of the reasoner to the given file. NOTE: currently dump_file prevents the reasoner from being re-used. This is a bug and will be amended

pub fn load_file(&mut self, filename: &str) -> Result<(), String>

Load the triples in the given file into the Reasoner. This currently accepts Turtle-formatted (.ttl) and NTriples-formatted (.n3) files. If you have issues loading in a Turtle file, try converting it to NTriples

pub fn reason(&mut self)

Perform OWL 2 RL-compatible reasoning on the triples currently loaded into the Reasoner

pub fn get_triples(&self) -> Vec<(Node, Node, Node)>

Returns the vec of triples currently contained in the Reasoner

pub fn view_output(&self) -> &[(Node, Node, Node)]

Returns the vec of triples currently contained in the Reasoner

pub fn get_triples_string(&mut self) -> Vec<(String, String, String)>

Returns the vec of triples currently contained in the Reasoner
