How to create a Vector of Strings in Rust ?

Answer

To create a vector of strings in Rust, you can use the vec! macro or manually initialize a vector with string elements.

✐ Examples

1 Create Vector of Strings using vec! Macro

In this example,

We use the vec! macro followed by square brackets [] to create a vector of strings.
Inside the square brackets, we list the strings separated by commas and enclosed in double quotes.
The vec! macro generates a vector with the specified strings.
We assign the result to a variable named str_vector.

Rust Program

let str_vector = vec!["apple", "banana", "cherry", "date", "grape"];
println!("{:?}", str_vector);

Output

["apple", "banana", "cherry", "date", "grape"]

2 Manually Initialize Vector of Strings

In this example,

We create an empty vector named str_vector of type Vec.
We use the push method to add strings one by one to the vector.
After adding all strings, the vector contains the desired sequence of strings.

Rust Program

let mut str_vector: Vec<String> = Vec::new();
str_vector.push("apple".to_string());
str_vector.push("banana".to_string());
str_vector.push("cherry".to_string());
str_vector.push("date".to_string());
str_vector.push("grape".to_string());
println!("{:?}", str_vector);

Output

["apple", "banana", "cherry", "date", "grape"]
