Enum OptionErrorKind 

pub enum OptionErrorKind {
    UnknownOption,
    AmbiguousOption,
    MissingValue,
    UnexpectedValue,
    SingleDashLongOption,
    HelpRequested,
}

What: Why Git would refuse the region before running the command. Why: The caller reports or forwards such a command line; it must never guess its facts.

In TS you’d write (pseudocode):

type OptionErrorKind = 'unknown-option' | 'ambiguous-option' | 'missing-value'
  | 'unexpected-value' | 'single-dash-long-option' | 'help-requested';

Variants

UnknownOption

Git prints unknown option or unknown switch and exits 129 (parse-options.c:1224-1233).

AmbiguousOption

An abbreviation matches several long options (578-587).

MissingValue

A value-taking option ends the region (60).

UnexpectedValue

--flag=value or --no-option=value (138-143).

SingleDashLongOption

-amend: letters that spell a long option; Git asks about two dashes (622-640).

HelpRequested

-h, --help, --help-all or a lone completion helper: Git prints and exits 0.
