Semantics for a piece of error information

Variants (Non-exhaustive)

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

`InvalidSubcommand`

The cause of the error

`InvalidArg`

The cause of the error

`PriorArg`

Existing arguments

`ValidValue`

Accepted values

`InvalidValue`

Rejected values

`ActualNumValues`

Number of values present

`ExpectedNumValues`

Number of allowed values

`MinValues`

Minimum number of allowed values

`SuggestedCommand`

Potential fix for the user

`SuggestedSubcommand`

Potential fix for the user

`SuggestedArg`

Potential fix for the user

`SuggestedValue`

Potential fix for the user

`TrailingArg`

Trailing argument

`Suggested`

Potential fix for the user

`Usage`

A usage string

`Custom`

An opaque message to the user
