The kind of failure an error reports, shared by every device.

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.

UserCancelled

The user declined on the device or dismissed a prompt.

AuthenticationRefused

The device’s login step failed without saying why.

HostUnavailable

The host could not get an answer from the user.

Locked

The device needs its PIN before it will answer.

NotReady

The device is reachable but not ready to run commands.

AlreadyUnlocked

A PIN step was requested but the device is already unlocked.

NotInitialized

The device has no wallet.

AlreadyInitialized

The device already has a wallet.

WrongPin

The PIN was wrong.

WrongNetwork

A key or address belongs to another network.

Duplicate

The item being created already exists on the device.

Unsupported

The device or firmware cannot run this command.

UnsupportedDisplayAddress

The device cannot display this address type.

MissingContext

The command needs data the caller did not supply.

InvalidInput

The caller’s data is malformed or was rejected as invalid.

Rejected

The device refused for a reason no other kind covers.

DeviceFailure

The device reported an internal failure.

Protocol

Host and device disagreed on the protocol.

UnexpectedResponse

A valid reply that is not the one expected.

Serialization

Bytes could not be encoded or decoded.

Encryption

Channel encryption or decryption failed.

Transport

I/O with the device or a helper service failed.

Disconnected

The device went away.

Other

No other kind applies.
