clone_dyn

Module :: clone_dyn

Derive to clone dyn structures.

The purpose of the crate is very simple, making dyn< Trait > clonable with minimum efforts and complexity, simply by applying to derive to the trait.

Alternative

There are few alternatives dyn-clone, dyn-clonable. Unlike alternatives, this solution is more compact and requires fewer efforts to use without loss of quality of the solution. Also, you can ask an inquiry and get answers, which is problematic in the case of alternatives.

Sample

#[ cfg( any( feature = "use_std", feature = "use_alloc" ) ) ]
{
  use clone_dyn::clone_dyn;

  #[ clone_dyn ]
  trait Trait1
  {
  }

  let vec = Vec::< Box< dyn Trait1 > >::new();
  let vec2 = vec.clone(); /* <- it does not work without `clone_dyn` */
}
