rustHow do I pass variable arguments in Rust?
Variable arguments in Rust can be passed using the std::env::args()
function. This function returns an iterator of the command line arguments passed to the program.
Example code
fn main() {
let args: Vec<String> = std::env::args().collect();
println!("{:?}", args);
}
Output example
["./my_program", "arg1", "arg2", "arg3"]
Code explanation
std::env::args()
: This function returns an iterator of the command line arguments passed to the program.let args: Vec<String> = std::env::args().collect();
: This line collects the arguments into a vector of strings.println!("{:?}", args);
: This line prints the vector of strings.
