# is_empty

![example workflow](https://github.com/puilp0502/is_empty/actions/workflows/test.yml/badge.svg)  
Easily check if the struct is empty.

## Usage

```rust
use is_empty::IsEmpty;

#[derive(IsEmpty)]
struct Foo {
    a: Option<String>,
    b: Option<String>,
}

let foo = Foo {
    a: Some("a".to_string()),
    b: None,
};
assert!(!foo.is_empty());

let bar = Foo {
   a: None,
   b: None,
};
assert!(bar.is_empty());
```
