# Usage

```rust

struct MyNewTypeStruct(String);

impl_more::impl_as_ref!(MyNewTypeStruct => String);

impl_more::impl_as_mut!(MyNewTypeStruct => String);

impl_more::impl_deref!(MyNewTypeStruct => String);

impl_more::impl_deref_mut!(MyNewTypeStruct);

// or, to deref through String too:

// impl_more::forward_deref_and_mut!(MyNewTypeStruct, ref str);

impl_more::impl_from!(String => MyNewTypeStruct);

impl_more::impl_into!(MyNewTypeStruct => String);

enum MyEnum {

    Bar,

    Qux,

}

impl_more::impl_display_enum!(MyEnum, Bar => "bar", Qux => "qux");

enum Coords {

    Xy(i64, i64),

    Xyz(i64, i64, i64),

}

impl_more::impl_display_enum!(

    Coords,

    Xy(x, y) => "{x}, {y}",

    Xyz(x, y, z) => "{x}, {y}, {z}",

);

#[derive(Debug)]

struct MyError(eyre::Report);

impl_more::forward_display!(MyError);

impl_more::forward_error!(MyError);

let err = MyError(eyre::eyre!("something went wrong"));

assert_eq!(err.source().unwrap().to_string(), "something went wrong");

#[derive(Debug)]

enum Err {

    Io(std::io::Error),

    Generic(String),

}

impl_more::impl_display_enum!(Err, Io(err) => "{err}", Generic(msg) => "{msg}");

impl_more::impl_error_enum!(Err, Io(err) => err);

```
