# Macros to build async version of an API

## Example

```rust
use build_async::{_async, _await};

#[_async] fn foo() {
    _await!(boo());
    _await!(x.zoo());
}
```

Will produce the following code:

```rust
fn foo() {
    boo();
    x.zoo();
}
async fn foo_async() {
    boo_async().await;
    x.zoo_async().await;
}
```

It works similarly with traits.
