Consume input as long as the predicate returns True, and return the consumed input. This parser does not fail. It will return an empty string if the predicate returns False on the first byte of input. Note: Because this parser does not fail, do not use it with combinators such as many, because such parsers loop until a failure occurs. Careless use will thus result in an infinite loop.

Consume input as long as the predicate returns True, and return the consumed input. This parser does not fail. It will return an empty string if the predicate returns False on the first character of input. Note: Because this parser does not fail, do not use it with combinators such as many, because such parsers loop until a failure occurs. Careless use will thus result in an infinite loop.

Consume input while the predicate returns True.

Consume input as long as the predicate returns True, and return the consumed input. This parser requires the predicate to succeed on at least one byte of input: it will fail if the predicate never returns True or if there is no input left.

Consume input until immediately after the predicate returns True, and return the consumed input. This parser will consume at least one Word8 or fail.
