Module :: derive_tools

Collection of derives which extend STD.

Sample

use derive_tools::*;

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

// derived Into
let src = Struct1 { a : 1, b : 3 };
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 );
