I've updated my nom
dependency from 4.x to 5.x version and found that macro take_until_and_consume
is deprecated. Changelog says:
"this can be replaced with
take_until
combined withtake
"
but I don't know how to emulate take_until_and_consume
with them.
Has anyone encountered such a problem with version updating or does anyone know how to do this?
I mean this deprecated macro take_until_and_consume
. And these new: take
and take_until
I believe this is straiforward but here a generic implementation:
fn take_until_and_consume<T, I, E>(tag: T) -> impl Fn(I) -> nom::IResult<I, I, E>
where
E: nom::error::ParseError<I>,
I: nom::InputTake
+ nom::FindSubstring<T>
+ nom::Slice<std::ops::RangeFrom<usize>>
+ nom::InputIter<Item = u8>
+ nom::InputLength,
T: nom::InputLength + Clone,
{
use nom::bytes::streaming::take;
use nom::bytes::streaming::take_until;
use nom::sequence::terminated;
move |input| terminated(take_until(tag.clone()), take(tag.input_len()))(input)
}
#[test]
fn test_take_until_and_consume() {
let r = take_until_and_consume::<_, _, ()>("foo")(&b"abcd foo efgh"[..]);
assert_eq!(r, Ok((&b" efgh"[..], &b"abcd "[..])));
}
