Function std::env::args

pub fn args() -> Args

Returns the arguments which this program was started with (normally passed via the command line).

The first element is traditionally the path to the executable, but it can be set to arbitrary text, and it may not even exist, so this property should not be relied upon for security purposes.

Panics

The returned iterator will panic during iteration if any argument to the process is not valid unicode. If this is not desired it is recommended to use the args_os function instead.

Examples

fn main() { use std::env; // Prints each argument on a separate line for argument in env::args() { println!("{}", argument); } }

use std::env;

// Prints each argument on a separate line
for argument in env::args() {
    println!("{}", argument);
}
