Variants (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.

Other(i32)

other error: {0}

Unsupported = -2

unsupported operation

OperationNotPermitted = -4

operation not permitted

BadParameter = -5

bad parameter
