Derive Macro fundamental_data_type::VariadicFrom

#[derive(VariadicFrom)]

Derive macro to implement default constructors From_0, From_1, From_2, From_3.

Sample :: struct instead of macro.

Write this

#[ derive( Make ) ]
pub struct IsTransparent( bool );

Instead of this

pub struct IsTransparent( bool );
impl From_0 for IsTransparent
{
  fn make0() -> Self
  {
    Self::default();
  }
}
impl From_1 for IsTransparent
{
  fn make1( src : bool ) -> Self
  {
    Self( src )
  }
}
