fn parse_step<E: From<Self::Error>>(
&mut self,
on_quad: &mut impl FnMut(Quad<'_>) -> Result<(), E>
) -> Result<(), E>
[src]
&mut self,
on_quad: &mut impl FnMut(Quad<'_>) -> 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.)
This method should be called as long as is_end
returns false.
May fails on errors caused by the parser itself or by the callback function on_quad
.
fn is_end(&self) -> bool
[src]
Returns true
if the file has been completely consumed by the parser.
Provided methods
fn parse_all<E: From<Self::Error>>(

) -> Result<(), E>
[src]
&mut self,
on_quad: &mut impl FnMut(Quad<'_>) -> Result<(), E>
) -> Result<(), E>
Parses the complete file and calls on_quad
each time a new quad is read.
May fails on errors caused by the parser itself or by the callback function on_quad
.

impl<T, E: From<P::Error>, F: FnMut(Quad<'_>) -> Result<T, E>, P: QuadsParser> Iterator for QuadsParserIterator<T, E, F, P> type Item = Result<T, E>;

iterator.
convert_triple
is a function converting Rio Triple
