Trait CopyRefVariadic

pub trait CopyRefVariadic: EitherRefVariadic + Sealed {
    // Required method
    fn copy_var(&self) -> Self::UnRefVar;
}

Copy a variadic of references EitherRefVariadic into a variadic of owned values EitherRefVariadic::UnRefVar.

let ref_var = var_expr!(&1, &"hello", &false);
let copy_var = ref_var.copy_var();
assert_eq!(var_expr!(1, "hello", false), copy_var);

Required Methods

fn copy_var(&self) -> Self::UnRefVar

Copy self per-value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
