Function uncons_while1

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