# into_inner

A simple trait and derive macro for extracting the inner value from tuple structs (newtypes) with a single field.

---

## Overview

The `into_inner` crate provides the `IntoInner` trait and a convenient `#[derive(IntoInner)]` macro for tuple structs with exactly one field. This allows you to easily extract the wrapped value from your newtypes without boilerplate.

---

## Usage

Add this to your `Cargo.toml`:

```toml
[dependencies]
into_inner = "0.1"
```

Then, in your code:

```rust
use into_inner::IntoInner;

#[derive(IntoInner)]
struct MyWrapper(String);

let wrapper = MyWrapper("Hello, world!".to_string());
let inner = wrapper.into_inner();
assert_eq!(inner, "Hello, world!");
```

---

## Features

- Derive macro for tuple structs with a single field.
- Compile-time errors for unsupported struct types.
- No dependencies outside of proc-macro ecosystem.
