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

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
