# `implicit-trait`

Create implicit traits to add methods to existing types.

```rust

use implicit_trait::implicit_trait;

// Assume Foo is from another crate, so we can't implement methods on it.

pub struct Foo {

    pub bar: i32,

    pub baz: String,

}

// Define new methods on Foo

#[implicit_trait]

impl FooExt for Foo {

    fn bar(&self) -> i32 {

        self.bar

    }

    fn baz(&self) -> &str {

        &self.baz

    }

}

// Use the new methods

fn main() {

    let foo = Foo {

        bar: 42,

        baz: "hello".to_string(),

    };

    assert_eq!(foo.bar(), 42);

    assert_eq!(foo.baz(), "hello");

}

```
