[−][src]Struct getopt::Opt
A single option.
For Opt(x, y)
:
x
isSome
character, orNone
if no option was found.y
isSome
string, orNone
if no argument was expected.
Example
use getopt::prelude::*; // args = ["program", "-abc", "foo"]; let optstring = "ab:c"; let mut state = State::new(); assert_eq!(Opt(Some('a'), None), getopt(&args, optstring, &mut state)?); assert_eq!( Opt(Some('b'), Some("c".to_string())), getopt(&args, optstring, &mut state)? ); assert_eq!(Opt(None, None), getopt(&args, optstring, &mut state)?);
