There are two types of flags in IMAP4rev1: System and keyword flags.

A system flag is a flag name that is pre-defined in RFC3501. All system flags begin with “" and certain system flags (\Deleted and \Seen) have special semantics. Flags that begin with “" but are not pre-defined system flags, are extension flags. Clients MUST accept them and servers MUST NOT send them except when defined by future standard or standards-track revisions.

A keyword is defined by the server implementation. Keywords do not begin with “" and servers may permit the client to define new ones in the mailbox by sending the “*” flag (FlagPerm::AllowNewKeywords) in the PERMANENTFLAGS response..

Note that a flag of either type can be permanent or session-only.

Variants

Seen

Message has been read (\Seen).

Answered

Message has been answered (\Answered).

Flagged

Message is “flagged” for urgent/special attention (\Flagged).

Deleted

Message is “deleted” for removal by later EXPUNGE (\Deleted).

Extension(FlagExtension<'a>)

Implementations

impl<'a> Flag<'a>

pub fn system<A>( value: A ) -> Result<Flag<'a>, FlagError<'a, <A as TryInto<Atom<'a>>>::Error>>where A: TryInto<Atom<'a>>,

pub fn extension<A>( value: A ) -> Result<Flag<'a>, FlagError<'a, <A as TryInto<Atom<'a>>>::Error>>where A: TryInto<Atom<'a>>,

Trait Implementations

impl<'a, 'arbitrary> Arbitrary<'arbitrary> for Flag<'a>where 'arbitrary: 'a,

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Flag<'a>, Error>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Flag<'a>, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl<'a> Clone for Flag<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Flag<'a>

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

Formats the value using the given formatter.

impl<'de, 'a> Deserialize<'de> for Flag<'a>

fn deserialize<__D>( __deserializer: __D ) -> Result<Flag<'a>, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Hash for Flag<'a>

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

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> IntoBoundedStatic for Flag<'a>

type Static = Flag<'static>

The target type is bounded by the 'static lifetime.

fn into_static(self) -> <Flag<'a> as IntoBoundedStatic>::Static

Convert an owned T into an owned T such that T: 'static.

impl<'a> PartialEq<Flag<'a>> for Flag<'a>

fn eq(&self, other: &Flag<'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.

impl<'a> Serialize for Flag<'a>

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> ToBoundedStatic for Flag<'a>

type Static = Flag<'static>

The target type is bounded by the 'static lifetime.

fn to_static(&self) -> <Flag<'a> as ToBoundedStatic>::Static

Convert an &T to an owned T such that T: 'static.

impl<'a> Eq for Flag<'a>

impl<'a> StructuralEq for Flag<'a>

impl<'a> StructuralPartialEq for Flag<'a>
