Struct Single

pub struct Single<T>(pub T);

Type constructor to wrap a another type into a tuple.

Sample :: struct instead of macro.

Sometimes it’s sufficient to use common type instead of defining a brand new one. You may use paramtetrized struct fundamental_data_type::Single< T > instead of macro fundamental_data_type::types! if that is the case.

use type_constructor::prelude::*;
let x = Single::< i32 >( 13 );
dbg!( x );
