Enumeration of all possible errors that can be reported by the program argument parser.

Variants

Uncaught(Uncaught)

Uncaught error forwarded from a report.

ShortsUnknown

The given short-option flags are unknown and cannot be handled. The flags are provided without the leading dash. Multiple consecutive flags can be reported in a single error.

Fields

shorts: &'args OsStr

FlagUnknown

The given flag is unknown and cannot be handled.

Fields

flag: &'args OsStr

FlagUnexpectedToggle

The given flag is known but was specified with the toggle-prefix no-, which is not valid for this flag.

Fields

flag: &'args OsStr

FlagUnexpectedValue

The given flag is known but was provided an inline value despite not taking any values.

Fields

flag: &'args OsStr

value: &'args OsStr

FlagNoValue

The given flag is known but was provided no value despite requiring one.

Fields

flag: &'args OsStr

FlagValueNotUtf8

A flag value was specified as invalid UTF-8, despite the flag requiring valid UTF-8 values.

Fields

flag: &'args OsStr

value: &'args OsStr

ParameterUnexpected

A command parameter was specified but the current command does not take parameters.

Fields

parameter: &'args OsStr

ParameterNotUtf8
