Make Engine without lifetime.

I need to store compiled once engines in struct
```rust

#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct RateLimitBodyJsonPath {
    pub engines: Vec<RsonpathEngine>,
}
```
but engine should keep reference with lifetime to query.

Is it possbile to make special Engine that pass query by value once and compile it to engine, and then use just engine to handle incoming json?
