tuples

Provides many useful tools related to tuples

• AsRef
• AsMut
• Mapping
• Iter
• IntoIter
• FromIter
• Meta Trait
• Shorthand Macro

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);

• 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);
