[−][src]Function pear::parsers::take_while_slice
pub fn take_while_slice<I, F>(input: &mut Pear<I>, f: F) -> Result<I::Slice, I> where
I: Input,
F: FnMut(&I::Slice) -> bool,
Consumes tokens while cond
matches on a continously growing slice
beginning at a length of 0
and ending when cond
fails. Returns the slice
between 0
and cond
failing. Errors if no such slice exists.
