How to get Item in a Vector at a Specific Index in Rust ?

Answer

To get an item in a Rust vector at a specific index, you can use indexing with square brackets.

✐ Examples

1 Access Item at Specific Index

In this example,

We create a vector of strings named my_vector.
We access an item at a specific index in the vector using square brackets [] and specify the index of the item we want to access.
The item at the specified index is returned.
We print the accessed item to the console.

Rust Program

fn main() {
    // Create a vector of strings
    let mut my_vector = vec!["apple", "banana", "cherry", "date"];

    // Access item at index 2
    let accessed_item = my_vector[2];

    // Print accessed item
    println!("Accessed item: {}", accessed_item);
}

Output

Accessed item: cherry
