The response codes for the protocol.

The response codes are based around IMAP’s response codes, and the top two bytes of the response indicates the type:

• 00: success
• 01: no (roughly, the request was understood, but not completed)
• 02: bad (roughly, the request was not understood)
• ff: extension message (dynamically allocated)

Variants

Success = 0

The request was successful. The response contains the requested data.

Continuation = 1

The request is incomplete, but is so far successful. The request should continue, referencing the ID of the last request.

NeedsAuthentication = 65_536

The request requires authentication.

The semantics for this message are equivalent to an HTTP 401 response.

Forbidden = 65_537

The message was not allowed.

The semantics for this message are equivalent to an HTTP 403 response.

Closing = 65_538

The server is shutting down.

Errno = 65_539

The message failed for a system error reason.

This is generally only useful for certain types of channels.

AuthenticationFailed = 65_540

Gone = 65_541

The other end of the channel has disappeared.

NotFound = 65_542

InternalError = 65_543

ChannelDead = 65_544

The channel has ceased to produce new data and this operation cannot complete.

Aborted = 65_545

The operation was aborted.

ContinuationNotFound = 65_546

There is no continuation with the specified parameters.

OutOfRange = 65_547

The result was out of range.

The semantics for this message are equivalent to ERANGE.

NoSpace = 65_548

There is no more space for the requested item.

Conflict = 65_549

The requested operation would conflict with something already existing.

The semantics for this message are equivalent to an HTTP 409 response.

Unlistable = 65_550

The contents of the object cannot be listed or specified by name.

For example, when using a Git-protocol credential helper, it is not possible to enumerate all credentials or pick a credential by ID.

NotEnabled = 131_072

The message type was not enabled.

NotSupported = 131_073

The message type or operation was not supported.

ParametersNotSupported = 131_074

The parameters were not supported.

Invalid = 131_075

The message type was received, but was not valid.

TooLarge = 131_076

The message was too large.

TooManyMessages = 131_077

There are too many pending messages.

InvalidParameters = 131_078

The parameters are supported, but not correct.

For example, if a selector is not valid for a channel, this message may be sent.

impl Ord for ResponseCode

fn cmp(&self, other: &ResponseCode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.
