rust vec to array
To convert a Rust Vec
to an array, you can use the into_boxed_slice
method followed by the into
method. Here's an example:
fn main() {
let vec = vec![1, 2, 3, 4, 5];
let array: Box<[i32]> = vec.into_boxed_slice().into();
println!("{:?}", array);
}
In this example, we first create a Vec
called vec
with some elements. Then, we call the into_boxed_slice
method on the Vec
to convert it into a boxed slice. Finally, we call the into
method on the boxed slice to convert it into an array. The resulting array is then printed using println!
.
Please note that the size of the array needs to be known at compile-time. If the size is dynamic or unknown, you may need to use a Vec
instead.
I hope this helps! Let me know if you have any further questions.
