Macro nom::tuple[][src]

macro_rules! tuple {
    ($i:expr, $($rest:tt)*) => { ... };
}

tuple!(I->IResult<I,A>, I->IResult<I,B>, ... I->IResult<I,X>) => I -> IResult<I, (A, B, ..., X)> chains parsers and assemble the sub results in a tuple.

The input type I must implement nom::InputLength.

This combinator will count how much data is consumed by every child parser and take it into account if there is not enough data

// the return type depends of the children parsers
named!(parser<&[u8], (u16, &[u8], &[u8]) >,
  tuple!(
    be_u16 ,
    take!(3),
    tag!("fg")
  )
);

assert_eq!(
  parser(&b"abcdefgh"[..]),
  Ok((
    &b"h"[..],
    (0x6162u16, &b"cde"[..], &b"fg"[..])
  ))
);
