Expand description
Declare your arguments using this macro.
Possible patterns:
use badargs::arg;
arg!(LongOrShort: "long-or-short", 's' -> bool);
arg!(OnlyLong: "only-long" -> bool);
arg!(pub OtherModule: "other-module" -> bool);
use badargs::arg;
arg!(Force: "force", 'f' -> bool);
is a shorthand for
use badargs::{arg, CliArg};
struct Force;
impl CliArg for Force {
type Content = bool;
fn long() -> &'static str {
"force"
}
fn short() -> Option<char> {
Some('f')
}
}
