Trait Tuple 

pub trait Tuple {
    type Arity: Arity;
}

A trait implemented for all tuple types up to arity 6 (or 12 with feature max-arity-12).

Required Associated Types

type Arity: Arity

Type-level representation of this tuple’s arity.

For example:

• () -> A0
• (T,) -> A1
• (T, U) -> A2

Implementations on Foreign Types

impl Tuple for ()

type Arity = A0

impl<T1> Tuple for (T1,)

type Arity = A1

impl<T1, T2> Tuple for (T1, T2)

type Arity = A2

impl<T1, T2, T3> Tuple for (T1, T2, T3)

type Arity = A3

impl<T1, T2, T3, T4> Tuple for (T1, T2, T3, T4)

type Arity = A4

impl<T1, T2, T3, T4, T5> Tuple for (T1, T2, T3, T4, T5)

type Arity = A5

impl<T1, T2, T3, T4, T5, T6> Tuple for (T1, T2, T3, T4, T5, T6)

type Arity = A6
