Struct GeneralizedNQuadsParser

pub struct GeneralizedNQuadsParser<R: BufRead> { /* private fields */ }

A N-Quads streaming parser parsing generalized quads.

It implements the GeneralizedQuadsParser trait. Using it requires to enable the generalized feature.

Implementations

impl<R: BufRead> GeneralizedNQuadsParser<R>

pub fn new(reader: R) -> Self

Trait Implementations

impl<R: BufRead> GeneralizedQuadsParser for GeneralizedNQuadsParser<R>

type Error = TurtleError

fn parse_step<E: From<TurtleError>>( &mut self, on_quad: &mut impl FnMut(GeneralizedQuad<'_>) -> Result<(), E>, ) -> Result<(), E>

Parses a small chunk of the file and calls on_quad each time a new quad is read. (A “small chunk” could be a line for an N-Quads parser.)

fn is_end(&self) -> bool

Returns true if the file has been completely consumed by the parser.

fn parse_all<E>( &mut self, on_quad: &mut impl FnMut(GeneralizedQuad<'_>) -> Result<(), E>, ) -> Result<(), E>

where E: From<Self::Error>,

Parses the complete file and calls on_quad each time a new quad is read.

fn into_iter<T, E, F>( self, convert_quad: F, ) -> GeneralizedQuadsParserIterator<T, E, F, Self>

where E: From<Self::Error>, F: FnMut(GeneralizedQuad<'_>) -> Result<T, E>, Self: Sized,

Converts the parser into a Result<T, E> iterator.
