Function combine::stream::uncons_while1

pub fn uncons_while1<Input: ?Sized, F>(
    input: &mut Input, 
    predicate: F
) -> ParseResult<Input::Range, Input::Error> where
    F: FnMut(Input::Token) -> bool,
    Input: RangeStream, 

Takes items from stream, testing each one with predicate returns a range of at least one items which passed predicate.

Note

This may not return PeekOk as it should uncons at least one token.
