rust get command line arguments
To get command line arguments in Rust, you can use the std::env::args
function. Here's an example:
use std::env;
fn main() {
let args: Vec<String> = env::args().collect();
// The first argument is the path to the executable
println!("Executable path: {}", args[0]);
// The rest of the arguments are the command line arguments
for arg in args.iter().skip(1) {
println!("Argument: {}", arg);
}
}
In this example, env::args
returns an iterator over the command line arguments. We collect the iterator into a Vec<String>
to access the arguments by index. The first argument (args[0]
) is the path to the executable, and the rest of the arguments can be accessed using a loop.
Please note that the above code assumes that you are using the std::env
module from the Rust standard library. If you are using a different environment or framework, the method for getting command line arguments may vary.
