A crate for quick and powerful constructor/builder generation in Rust. Dual

licensed under `MIT OR Apache-2.0`. Example:

```rust

use scones::{make_builder, make_constructor};

#[make_builder]

#[make_constructor]

struct Basic {

    int: i32,

    string: String,

}

let instance = Basic::new(int, string);

let instance = BasicBuilder::new().string("str".to_owned()).int(12345).build();

// Triggers a compile-time error because we have not specified all fields yet:

// let instance = BasicBuilder::new().build();

#[make_constructor]

#[make_constructor(pub new_identical(shared: i32))]

pub struct MultipleConstructors {

    #[value(shared for new_identical)]

    pub a: i32,

    #[value(shared for new_identical)]

    pub b: i32,

    #[value(shared for new_identical)]

    pub c: i32,

    #[value(true)]

    #[value(false for new)]

    pub identical: bool,

}

let instance = MultipleConstructors::new(1, 2, 3);

let instance = MultipleConstructors::new_identical(123);

#[make_constructor]

#[make_constructor(pub default_number)]

#[make_builder((field_1?))]

pub struct TupleStruct(

    #[value(30 for default_number)] i32,

    #[value("Unnamed".to_owned() for TupleStructBuilder)] String,

);

let instance = TupleStruct::default_number(field_1);

let instance = TupleStructBuilder::new().field_0(12345).build();

```
