Trait Implementations

impl<RDF> Clone for SetFocus<RDF>

where RDF: FocusRDF + Clone, RDF::Term: Clone,

fn clone(&self) -> SetFocus<RDF>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<RDF> Debug for SetFocus<RDF>

where RDF: FocusRDF + Debug, RDF::Term: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<RDF> RDFNodeParse<RDF> for SetFocus<RDF>

where RDF: FocusRDF,

type Output = ()

The type which is returned if the parser is successful.

fn parse_impl(&mut self, rdf: &mut RDF) -> PResult<()>

Parses the current focus node without modifying the state

fn parse(&mut self, node: &IriS, rdf: RDF) -> PResult<Self::Output>

Entry point to the parser. It moves the focus node of rdf to node and runs the parser.

fn by_ref(&mut self) -> ByRef<'_, Self>

where Self: Sized,

fn flat_map<F, O>(self, f: F) -> FlatMap<Self, F>

where Self: Sized, F: FnMut(Self::Output) -> PResult<O>,

Uses f to map over the output of self. If f returns an error the parser fails.

fn and_then<F, O, E>(self, f: F) -> AndThen<Self, F>

where Self: Sized, F: FnMut(Self::Output) -> Result<O, E>, E: Into<RDFParseError>,

Parses with self and applies f on the result if self parses successfully. f may optionally fail with an error which is automatically converted to a RDFParseError.

fn map<F, B>(self, f: F) -> Map<Self, F>

where Self: Sized, F: FnMut(Self::Output) -> B,

Uses f to map over the parsed value.

fn and<P2>(self, parser: P2) -> (Self, P2)

where Self: Sized, P2: RDFNodeParse<RDF>,

Parses self followed by p. Succeeds if both parsers succeed, otherwise fails. Returns a tuple with both values on success.

fn then<N, F>(self, f: F) -> Then<Self, F>

where Self: Sized, F: FnMut(Self::Output) -> N, N: RDFNodeParse<RDF>,

Parses using self and then passes the value to f which returns a parser used to parse the rest of the input.

fn then_ref<N, F>(self, f: F) -> ThenRef<Self, F>

where Self: Sized, F: FnMut(&Self::Output) -> N, N: RDFNodeParse<RDF>,

Parses using self and then passes a reference to the value to f which returns a parser used to parse the rest of the input.

fn then_mut<N, F>(self, f: F) -> ThenMut<Self, F>

where Self: Sized, F: FnMut(&mut Self::Output) -> N, N: RDFNodeParse<RDF>,

Parses using self and then passes a reference to the mutable value to f which returns a parser used to parse the rest of the input.

fn or<P2>(self, parser: P2) -> Or<Self, P2>

where Self: Sized, P2: RDFNodeParse<RDF, Output = Self::Output>,

Returns a parser which attempts to parse using self. If self fails then it attempts parser.

fn focus(self, node: &RDF::Term) -> SetFocus<RDF>

where Self: Sized,

Sets the focus node and returns ()

fn with<P, A>(self, parser: P) -> With<Self, P>

where Self: Sized, P: RDFNodeParse<RDF, Output = A>,

Discards the value of the current parser and returns the value of parser
