@ozankabak Are you suggesting something like this?
```rust
use std::ops::Deref;
struct LimitedVector(Vec<Option<bool>>);
impl LimitedVector {
fn new(initial: Vec<Option<bool>>) -> Result<Self, &'static str> {
if initial.len() >= 2 {
Ok(LimitedVector(initial))
} else {
Err("Initial vector length must be 2 or more")
}
}
}
impl Deref for LimitedVector {
type Target = Vec<Option<bool>>;
fn deref(&self) -> &Self::Target {
&self.0
}
}
// Example usage:
fn main() {
let initial_vector = vec![Some(true), None];
match LimitedVector::new(initial_vector) {
Ok(limited_vector) => {
println!("Length: {}", limited_vector.len()); // Length: 2
println!("Elements: {:?}", *limited_vector); // Elements:
[Some(true), None]
}
Err(err) => println!("Error: {}", err),
}
}
```
