Examples

• map rust let a = (1, 2, 3); let b = a.map(|v| v * 3); assert_eq!(b, (3, 6, 9));
• mapN rust let a = (1, 2, 3, 4, 5); let b = a.map3(|v| v * 5); assert_eq!(b, (1, 2, 3, 20, 5));
• as_ref rust let t = (5, 6, 7); let (a, b, c) = t.as_ref(); assert_eq!(*a, 5); assert_eq!(*b, 6); assert_eq!(*c, 7);
• cloned rust let a = (&1, &2, &3); let b = a.cloned(); assert_eq!(b, (1, 2, 3))
• flatten rust let a = ((1, 2, 3), (4, 5, 6), (7, 8, 9)); let b = a.flatten(); assert_eq!(b, (1, 2, 3, 4, 5, 6, 7, 8, 9));

• meta ```rust let a = (1, 2, 3, 4, 5); assert_eq!(a.arity(), 5);

  let b = (); assert_eq!(b.arity(), 0); ```

• iter rust let a = (1, 2, 3) .into_iter() .map(|v| v * 3) .collect_tuple::<tuple![3;]>(); let b: (i32, i32, i32) = (3, 6, 9); assert_eq!(a, b); rust let a = (1, 2, 3) .into_iter() .map(|v| v * 3) .try_collect_tuple::<tuple![3;]>(); let b: Option<(i32, i32, i32)> = Some((3, 6, 9)); assert_eq!(a, b); rust let a = (1, 2, 3) .into_iter() .map(|v| v * 3) .collect_tuple_try::<tuple![3;]>(); let b: (Option<i32>, Option<i32>, Option<i32>) = (Some(3), Some(6), Some(9)); assert_eq!(a, b);

• transpose ```rust let a = Some((1, 2, 3)).transpose(); assert_eq!(a, (Some(1), Some(2), Some(3)));

  let b = (Some(1), Some(2), Some(3)).transpose(); asserteq!(b, Some((1, 2, 3))); rust let a: (Resulteq!(b, Ok((1, 2, 3))); rust let a: (Result, Result, Result) = (Ok(1), Err(-1), Ok(3)); let b: Result<(u8, u8, u8), i64> = a.transpose(); assert_eq!(b, Err(-1)); ```

• combin ```rust let a = (1, 2).push(3); assert_eq!(a, (1, 2, 3));

  let b = (2, 1).left(3); assert_eq!(b, (3, 2, 1));

  let c = (1, 2, 3).concat((4, 5, 6)); assert_eq!(c, (1, 2, 3, 4, 5, 6)) ```
