rustHow do I use a variable number of arguments in Rust?

Rust supports variable number of arguments using the std::env::args() function. This function returns an iterator over the arguments passed to the program.

fn main() {
    let args: Vec<String> = std::env::args().collect();
    println!("{:?}", args);
}

Output example

["/usr/local/bin/rustrun", "my_program.rs", "arg1", "arg2"]

The code above collects the arguments passed to the program into a vector of strings.

1. std::env::args(): This function returns an iterator over the arguments passed to the program.
2. collect(): This method collects the iterator into a vector of strings.
