Expand description
A parser returning Quad
.
Associated Types
Required methods
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
.
Provided methods
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>;
Converts the parser into a Result<T, E>
iterator.
convert_triple
is a function converting Rio Triple
to T
.
