Tuco

Tuco can automatically generate tuple representations of simple types. This is helpful if you want to create an API using plain types. Or if you want to provide an easy way to convert between types.

Using #[derive(Tuco)] Will automatically derive Tuco and generate a tuple representation of your struct and assign it to the associated type Tuco::Tuple

Tuco can be used in places where data serialization is used with some differences:

• Conversion operations are validated at compile time.
• Since tuples are unnamed, any matching tuple shape may be used to construct your type. No further integrity checks are applied at this time.
• Tuco does not automatically serialize your types to string data.

Todo

• Support structs with named fields
• Support structs with unnamed fields
• Support more complex structs
• Documentation
• Compiler errors / Tests

Example

    #[derive(Tuco, Debug)]
    struct MyStruct {
        a: i32,
        b: String,
        c: bool,
    }

    #[derive(Tuco, Debug)]
    struct MyOtherStruct {
        x: i32,
        y: String,
        z: bool,
    }

    #[derive(Tuco, Debug)]
    struct MyNestedStruct {
        x: i32,
        #[tuco]
        y: MyStruct,
        z: bool,
    }

    #[derive(Tuco, Debug)]
    struct MyOtherNestedStruct {
        x: i32,
        #[tuco]
        y: MyOtherStruct,
        z: bool,
    }

    fn nested_struct() {
        let my_nested_struct = MyNestedStruct {
            x: 10,
            y: MyStruct {
                a: 1,
                b: "qwe".to_string(),
                c: true,
            },
            z: false,
        };

        println!("{:?}", my_nested_struct);

        let my_other_struct = MyOtherNestedStruct::from_tuco(my_nested_struct);

        println!("{:?}", my_other_struct);
    } 

Output:

    MyNestedStruct { x: 10, y: MyStruct { a: 1, b: "qwe", c: true }, z: false }
    MyOtherNestedStruct { x: 10, y: MyOtherStruct { x: 1, y: "qwe", z: true }, z: false }
