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::Asterisk) in the PERMANENTFLAGS response..

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

Implementations

impl<'a> Flag<'a>

pub fn system(atom: Atom<'a>) -> Self

pub fn keyword(atom: Atom<'a>) -> Self

Trait Implementations

impl<'a> Arbitrary<'a> for Flag<'a>

fn arbitrary(u: &mut Unstructured<'a>) -> Result<Self>

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

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, 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.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

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 duplicate 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

Formats the value using the given formatter.

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

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Display for Flag<'a>

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

Formats the value using the given formatter.

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

type Static = Flag<'static>

The target type is bounded by the 'static lifetime.

fn into_static(self) -> Self::Static

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

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

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

Tests for self and other values to be equal, and is used by ==.

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

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::Ok, __S::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) -> Self::Static

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

impl<'a> TryFrom<&'a str> for Flag<'a>

type Error = ValidationError

The type returned in the event of a conversion error.

fn try_from(value: &'a str) -> Result<Self, Self::Error>

Performs the conversion.
