Module :: derive_tools

Basic use-case

# #[ cfg( all( feature = "derive_from", feature = "derive_display", feature = "derive_from_str" ) ) ]
{
  use derive_tools::*;

  #[ derive( From, Display, FromStr, PartialEq, Debug ) ]
  #[ display( "{0}" ) ]
  struct Struct1( i32 );

  // derived From
  let src : Struct1 = 42.into();
  let exp = Struct1( 42 );
  assert_eq!( src, exp );

  // derived Display
  let src = Struct1( 42 );
  let got = format!( "{}", src );
  let exp = "42";
  println!( "{}", got );
  assert_eq!( got, exp );

  // derived FromStr  
  use std::str::FromStr;
  let src = Struct1::from_str( "42" );
  let exp = Ok( Struct1( 42 ) );
  assert_eq!( src, exp );

}
