Function palaver::env::args

pub fn args() -> Option<Vec<String>>

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

The first element is traditionally the path of 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.

Errors

This will return None if get_env can't acquire them. Please file an issue.

Panics

Will panic if any argument to the process is not valid unicode. If this is not desired, consider using the args_os function.

Examples

use palaver::env;

// Prints each argument on a separate line
for argument in env::args().expect("Couldn't retrieve arguments") {
    println!("{}", argument);
}
