Trait Implementations

impl RDFParser for TurtleParser

fn uri(u: &str) -> Parsed<Uri>

Parses a Uri from a string

Errors

Returns a ParserError if the string is not a valid URI

Examples

let uri = TurtleParser::uri("<http://example.com/rdf/Person>")?;
let uri = TurtleParser::uri("<#Person>")?;
let uri = TurtleParser::uri("ex:Person")?;
let uri = TurtleParser::uri(":Person")?;

fn resource(r: &str) -> Parsed<Resource>

Parses a Resource from a string. A wrapper around RDFParser::uri() specifically for RDF resources.

Errors

Returns a ParserError if the string is not a valid Resource

Examples

let res = TurtleParser::resource("<http://example.com/rdf/Person>")?;
let res = TurtleParser::resource("<#Person>")?;
let res = TurtleParser::resource("ex:Person")?;
let res = TurtleParser::resource(":Person")?;

fn relationship(r: &str) -> Parsed<Relationship>

Parses a Relationship from a string. A wrapper around RDFParser::uri() specifically for RDF relationships.

Errors

Returns a ParserError if the string is not a valid Relationship

Examples

let rel = TurtleParser::relationship("<http://example.com/foaf#knows>")?;
let rel = TurtleParser::relationship("<#knows>")?;
let rel = TurtleParser::relationship("foaf:knows")?;
let rel = TurtleParser::relationship(":knows")?;

fn object(o: &str) -> Parsed<Object>

Parses an Object from a string.

Errors

Returns a ParserError if the string is not a valid Object

Examples

let obj = TurtleParser::object(r#""john@example.com""#)?;
let obj = TurtleParser::object(r#""すし"@jp"#)?;
let obj = TurtleParser::object("foaf:Person")?;

fn triple(t: &str) -> Parsed<Vec<Triple>>

Parses a Vec<Triple> from a string.

Errors

Returns a ParserError if the string is not a valid Triple or collection of triples.

Examples

let triple = TurtleParser::triple(r#"ex:John foaf:mbox "john@example.com" ."#)?;
let triple = TurtleParser::triple(r#"[ foaf:name "Alice" ] foaf:knows [ foaf:name "Bob" ] ."#)?;

fn graph(g: &str) -> Parsed<Graph>

Parses a Graph from a string (typically a file).

Errors

Returns a ParserError if the string is not a valid Graph.

Examples

let triple = TurtleParser::graph(r#"
    @base <http://example.com/> .
    @prefix foaf: <http://xmlns.com/foaf/0.1/> .
    @prefix owl: <http://www.w3.org/2002/07/owl#> .

    :John foaf:mbox "john@example.com" .
    [ foaf:mbox "john@example.com" ] owl:sameAs :John .
"#)?;

fn from_file(path: &str) -> Parsed<Graph>

Acts as a wrapper around RDFParser::graph() that automatically reads and parses a file.
