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