How to Append an Item to a Vector in Rust - Step by Step Examples

How to Append an Item to a Vector in Rust ?

Answer

To append an item to a vector in Rust, you can use the push() method provided by the Vec type. This method allows you to add elements to the end of the vector dynamically.

✐ Examples

1 Append Item to Vector using push method

In this example,

We create a vector named vec with some initial elements.
We use the push method to append a new item to the vector.

Rust Program

// Create a vector with initial elements
let mut vec = vec![1, 2, 3];

// Append item to the vector using push method
vec.push(4);

// Print the modified vector
println!("{:?}", vec);

Output

[1, 2, 3, 4]

2 Append String to Vector using push method

In this example,

We create a vector of strings named strings with some initial strings.
We use the push method to append a new string to the vector.

Rust Program

// Create a vector of strings with initial strings
let mut strings = vec!["hello", "world"];

// Append a string to the vector using push method
strings.push("rust");

// Print the modified vector
println!("{:?}", strings);

Output

["hello", "world", "rust"]
