encode base64 rust

To encode a string to base64 in Rust, you can use the base64 crate. First, add the base64 crate to your Cargo.toml file:

[dependencies]
base64 = "0.13.0"

Then, in your Rust code, you can use the encode function from the base64 crate to encode a string to base64. Here's an example:

use base64;

fn main() {
    let input = "Hello, World!";
    let encoded = base64::encode(input);
    println!("Encoded: {}", encoded);
}

This code will encode the string "Hello, World!" to base64 and print the encoded result. You can replace the input variable with the string you want to encode.
