Enum getopts::Fail_

pub enum Fail_ {
    ArgumentMissing(~str),
    UnrecognizedOption(~str),
    OptionMissing(~str),
    OptionDuplicated(~str),
    UnexpectedArgument(~str),
}

The type returned when the command line does not conform to the expected format. Call the to_err_msg method to retrieve the error as a string.

Variants

`ArgumentMissing`	The option requires an argument but none was passed.
`UnrecognizedOption`	The passed option is not declared among the possible options.
`OptionMissing`	A required option is not present.
`OptionDuplicated`	A single occurence option is being used multiple times.
`UnexpectedArgument`	There's an argument being passed to a non-argument option.
