### rust

安装：在项目目录下运行 `cargo add oml`

```rust
fn main() {
    let oml_str = r#"
[hello]
value = 12
name = $"hello world {value + 12}"
"#;
    let mut root = OmlExpr::from_str(oml_str).unwrap();
    root["hello"]["value"].set_int(30);
    let root = root.evalute().unwrap();
    println!("{}", root["hello"]["name"].as_str()); // hello world 42
}
```
