How to Convert a Vector of Floats to a Vector of Strings in Rust ?

Answer

To convert a vector of floats to a vector of strings in Rust, you can use the `to_string()` method.

✐ Examples

1 Convert Vector of Floats to Vector of Strings

In this example,

We create a vector of floats named float_vector.
We map each float in float_vector to its string representation using the to_string() method.
We collect the mapped strings into a vector.

Rust Program

let float_vector = vec![1.5, 2.5, 3.5, 4.5, 5.5];
let str_vector: Vec<String> = float_vector.iter().map(|&f| f.to_string()).collect();
println!("{:?}", str_vector);

Output

["1.5", "2.5", "3.5", "4.5", "5.5"]
