### Basic use-case

<!-- {{# generate.module{} #}} -->

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

  #[ derive( From, InnerFrom, Display, FromStr, PartialEq, Debug ) ]
  #[ display( "{a}-{b}" ) ]
  struct Struct1
  {
    a : i32,
    b : i32,
  }

  // derived InnerFrom
  let src = Struct1 { a : 1, b : 3 };
  let got : ( i32, i32 ) = src.into();
  let exp = ( 1, 3 );
  assert_eq!( got, exp );

  // derived From
  let src : Struct1 = ( 1, 3 ).into();
  let got : ( i32, i32 ) = src.into();
  let exp = ( 1, 3 );
  assert_eq!( got, exp );

  // derived Display
  let src = Struct1 { a : 1, b : 3 };
  let got = format!( "{}", src );
  let exp = "1-3";
  println!( "{}", got );
  assert_eq!( got, exp );

  // derived FromStr
  use std::str::FromStr;
  let src = Struct1::from_str( "1-3" );
  let exp = Ok( Struct1 { a : 1, b : 3 } );
  assert_eq!( src, exp );

}
```
