get length of vector rust
To get the length of a vector in Rust, you can use the len()
method. Here's an example:
fn main() {
let my_vector = vec![1, 2, 3, 4, 5];
let length = my_vector.len();
println!("Length of the vector: {}", length);
}
In this example, we create a vector called my_vector
with some elements. We then use the len()
method to get the length of the vector and store it in the variable length
. Finally, we print the length of the vector using println!()
.
