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
ActualNumOccurrences
Number of occurrences present
MaxOccurrences
Maximum number of allowed occurrences
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
Usage
A usage string
Custom
An opaque message to the user
