A response code consists of data inside square brackets in the form of an atom, possibly followed by a space and arguments. The response code contains additional information or status codes for client software beyond the OK/NO/BAD condition, and are defined when there is a specific action that a client can take based upon the additional information.

The currently defined response codes are:

Variants

Alert

ALERT

The human-readable text contains a special alert that MUST be presented to the user in a fashion that calls the user’s attention to the message.

BadCharset

Fields

allowed: Vec<Charset<'a>>

BADCHARSET

Optionally followed by a parenthesized list of charsets. A SEARCH failed because the given charset is not supported by this implementation. If the optional list of charsets is given, this lists the charsets that are supported by this implementation.

Capability(NonEmptyVec<Capability<'a>>)

CAPABILITY

Followed by a list of capabilities. This can appear in the initial OK or PREAUTH response to transmit an initial capabilities list. This makes it unnecessary for a client to send a separate CAPABILITY command if it recognizes this response.

Parse

PARSE

The human-readable text represents an error in parsing the [RFC-2822] header or [MIME-IMB] headers of a message in the mailbox.

PermanentFlags(Vec<FlagPerm<'a>>)

PERMANENTFLAGS

Followed by a parenthesized list of flags, indicates which of the known flags the client can change permanently. Any flags that are in the FLAGS untagged response, but not the PERMANENTFLAGS list, can not be set permanently. If the client attempts to STORE a flag that is not in the PERMANENTFLAGS list, the server will either ignore the change or store the state change for the remainder of the current session only. The PERMANENTFLAGS list can also include the special flag *, which indicates that it is possible to create new keywords by attempting to store those flags in the mailbox.

ReadOnly

READ-ONLY

The mailbox is selected read-only, or its access while selected has changed from read-write to read-only.

ReadWrite

READ-WRITE

The mailbox is selected read-write, or its access while selected has changed from read-only to read-write.

TryCreate

TRYCREATE

An APPEND or COPY attempt is failing because the target mailbox does not exist (as opposed to some other reason). This is a hint to the client that the operation can succeed if the mailbox is first created by the CREATE command.

UidNext(NonZeroU32)

UIDNEXT

Followed by a decimal number, indicates the next unique identifier value. Refer to section 2.3.1.1 for more information.

UidValidity(NonZeroU32)

UIDVALIDITY

Followed by a decimal number, indicates the unique identifier validity value. Refer to section 2.3.1.1 for more information.

Unseen(NonZeroU32)

UNSEEN

Followed by a decimal number, indicates the number of the first message without the \Seen flag set.

Other(CodeOther<'a>)

Additional response codes defined by particular client or server implementations SHOULD be prefixed with an “X” until they are added to a revision of this protocol. Client implementations SHOULD ignore response codes that they do not recognize.

Implementations

impl<'a> Code<'a>

pub fn badcharset(allowed: Vec<Charset<'a>>) -> Self

pub fn capability<C>(caps: C) -> Result<Self, C::Error>where C: TryInto<NonEmptyVec<Capability<'a>>>,

pub fn permanentflags(flags: Vec<FlagPerm<'a>>) -> Self

pub fn uidnext(uidnext: u32) -> Result<Self, TryFromIntError>

Trait Implementations

impl<'a> Clone for Code<'a>

fn clone(&self) -> Code<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Code<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Encode for Code<'a>

fn encode(&self, writer: &mut impl Write) -> Result<()>

fn encode_detached(&self) -> Result<Vec<u8>>

impl<'a> Hash for Code<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq<Code<'a>> for Code<'a>

fn eq(&self, other: &Code<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
