Function clone_into_box

pub fn clone_into_box<T>(ref_dyn: &T) -> Box<T>
where
    T: CloneDyn + ?Sized,

Clone boxed dyn.

Clones a dynamically sized trait object into a Box< T >.

Example

use clone_dyn_types::{ CloneDyn, clone_into_box };

#[ derive( Clone ) ]
struct MyStruct
{
  value : i32,
}

trait MyTrait : CloneDyn
{
  fn val( &self ) -> i32;
}

impl MyTrait for MyStruct
{
  fn val( &self ) -> i32
  {
    self.value
  }
}

#[ allow( non_local_definitions ) ]
impl < 'c > Clone
for Box< dyn MyTrait + 'c >
{
  #[ inline ]
  fn clone( &self ) -> Self { clone_into_box( &**self ) }
}

#[ allow( non_local_definitions ) ]
impl < 'c > Clone
for Box< dyn MyTrait + Send + 'c >
{
  #[ inline ]
  fn clone( &self ) -> Self { clone_into_box( &**self ) }
}

#[ allow( non_local_definitions ) ]
impl < 'c > Clone
for Box< dyn MyTrait + Sync + 'c >
{
  #[ inline ]
  fn clone( &self ) -> Self { clone_into_box( &**self ) }
}

#[ allow( non_local_definitions ) ]
impl < 'c > Clone

{
  #[ inline ]
  fn clone( &self ) -> Self { clone_into_box( &**self ) }
}

let cloned : Box< dyn MyTrait > = clone_into_box( &MyStruct { value : 42 } );
