Trait PrimaryKeyArity 

pub trait PrimaryKeyArity {
    const ARITY: usize;
}

How many columns this Primary Key comprises

Required Associated Constants

const ARITY: usize

Arity of the Primary Key

Dyn Compatibility

This trait is not dyn compatible.

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