# Impl Into Macro


The implementation of trait [Into](std::convert::Into).

> See more macros: [docs](https://docs.rs/macron), [repository](https://github.com/fuderis/macron-rs).

## Examples:


### Struct

```rust
#[derive(Into, Debug, PartialEq)]

pub struct Email(String);

let email = Email("user@example.com".to_string());
let email_str: String = email.into();

assert_eq!("user@example.com", &email_str);
```

### Enum

```rust
#[derive(Into)]

pub enum Number {
    Integer(i32),

    #[into(i32, expr = value as i32)]
    Float(f64),

    #[into(i32, expr = 0)]
    Null,

    #[into(i32, with = Self::from_str)]
    Stringify(&'static str),
}

impl Number {
    fn from_str(s: &str) -> i32 {
        s.parse::<i32>().unwrap_or(0)
    }
}

assert_eq!(42, Number::Integer(42).into());
assert_eq!(3, Number::Float(3.14).into());
assert_eq!(0, Number::Null.into());
assert_eq!(15, Number::Stringify("15").into());
```
