`bon` is a Rust crate for generating compile-time-checked builders for functions and structs.

Visit the [guide for a complete overview of the crate](https://elastio.github.io/bon/docs/guide/overview).

## Quick example

`bon` can turn a function with positional parameters into a function with "named" parameters via a builder. It's as easy as placing the `#[builder]` macro on top of it.

```rust
use bon::builder;

#[builder]
fn greet(name: &str, age: u32) -> String {
    format!("Hello {name} with age {age}!")
}

let greeting = greet()
    .name("Bon")
    .age(24)
    .call();

assert_eq!(greeting, "Hello Bon with age 24!");
```
