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

ValidSubcommand

Accepted subcommands

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
