Sample

use former::Former;

#[derive( Debug, PartialEq, Former )]
pub struct Structure1
{
  int_1 : i32,
  string_1 : String,
  vec_1 : Vec< i32 >,
  hashmap_strings_1 : std::collections::HashMap< String, String >,
  int_optional_1 : core::option::Option< i32 >,
  string_optional_1 : Option< String >,
}

let struct1 = Structure1::former()
.int_1( 13 )
.string_1( "Abcd".to_string() )
.vec_1().replace( vec![ 1, 3 ] ).end()
.hashmap_strings_1().insert( "k1", "v1" ).insert( "k2", "v2" ).end()
.string_optional_1( "dir1" )
.form();
dbg!( &struct1 );
