Provides a new type called Named Tups that can be called using the [`tup!`] macro. Named Tups are structs that can
contain a set of named arguments, effectively they work like normal tuples that can be accessed and created using an
actual name.

[`tup!`]: https://docs.rs/named-tup/latest/named-tup/macro.tup.html

The idea of named tuples is to provide a way to quickly iterate on ideas without having to create a builder struct or
losing the ability to type check at compile time. Named tuples also allow the creation of default values that can
replace nonexistent arguments.

```toml
[dependencies]
named-tup = "0.1.0"

[package.metadata.inwelling]
named-tup-derive = true
```

## Examples

```rust
use named_tup::tup;
let count = 5;

// This will have the type of tup!(count: i32, ingredients: [&str; 3], eggs: bool)
let cakes = tup!(count, ingredients: ["milk", "flower", "sugar"], eggs: true);

// We can just add a price afterwards
let mut cakes = cakes + tup!(price: 3);
// And now it has the type of tup!(eggs: bool, ingredients: [&str; 3], count: i32, price: i32)

// Once the price is in the tup we can just update it!
cakes.price = 4;

// Will print tup { count: 5, eggs: true, ingredients: ["milk", "flower", "sugar"], price: 4 }
println!("{cakes:?}");
```

To use defaults just annotate the item where you set a field
with [`#[tup_default]`](https://docs.rs/named-tup/latest/named-tup/attr.tup_default.html). Additionally since the
defaulted [`tup!`] is a type you need to convert into it by calling [`.into_tup()`] which can be accessed through
the [`TupInto`] trait.

[`.into_tup()`]: https://docs.rs/named-tup/latest/named-tup/trait.TupInto.html

[`TupInto`]: https://docs.rs/named-tup/latest/named-tup/trait.TupInto.html

```rust
use named_tup::{tup, tup_default, TupInto};

let options = tup!(read: false, write: true);

// Converts to tup!(read: false, write: true, create: false, timeout: 5)
open_file("main.rs", options.into_tup());

#[tup_default]
fn open_file(
    path: &str,
    options: tup!(
        read: bool = true,
        write: bool = false,
        create: bool = false,
        timeout: i32 = 5
    ))
{
    // Open the file
}
```

To test the crate enable the feature `dev-test`.

## Roadmap

- Write some more tests
- Serialise and Deserialise using Serde
- Provide nice looking types for cargo doc
