Message data item.

Variants

Body(BodyStructure<'a>)

A form of BODYSTRUCTURE without extension data.

BODY

BodyExt

The body contents of the specified section.

8-bit textual data is permitted if a [CHARSET] identifier is part of the body parameter parenthesized list for this section. Note that headers (part specifiers HEADER or MIME, or the header portion of a MESSAGE/RFC822 part), MUST be 7-bit; 8-bit characters are not permitted in headers. Note also that the [RFC-2822] delimiting blank line between the header and the body is not affected by header line subsetting; the blank line is always included as part of header data, except in the case of a message which has no body and no blank line.

Non-textual data such as binary data MUST be transfer encoded into a textual form, such as BASE64, prior to being sent to the client. To derive the original binary data, the client MUST decode the transfer encoded string.

BODY[<section>]<<origin octet>>

Fields

section: Option<Section<'a>>

The specified section.

origin: Option<u32>

If the origin octet is specified, this string is a substring of the entire body contents, starting at that origin octet. This means that BODY[]<0> MAY be truncated, but BODY[] is NEVER truncated.

Note: The origin octet facility MUST NOT be used by a server in a FETCH response unless the client specifically requested it by means of a FETCH of a BODY[<section>]<<partial>> data item.

data: NString<'a>

The string SHOULD be interpreted by the client according to the content transfer encoding, body type, and subtype.

BodyStructure(BodyStructure<'a>)

The [MIME-IMB] body structure of a message.

This is computed by the server by parsing the [MIME-IMB] header fields, defaulting various fields as necessary.

BODYSTRUCTURE

Envelope(Envelope<'a>)

The envelope structure of a message.

This is computed by the server by parsing the [RFC-2822] header into the component parts, defaulting various fields as necessary.

ENVELOPE

Flags(Vec<FlagFetch<'a>>)

A list of flags that are set for a message.

FLAGS

InternalDate(DateTime)

A string representing the internal date of a message.

INTERNALDATE

Rfc822(NString<'a>)

Equivalent to BODY[].

RFC822

Rfc822Header(NString<'a>)

Equivalent to BODY[HEADER].

Note that this did not result in \Seen being set, because RFC822.HEADER response data occurs as a result of a FETCH of RFC822.HEADER. BODY[HEADER] response data occurs as a result of a FETCH of BODY[HEADER] (which sets \Seen) or BODY.PEEK[HEADER] (which does not set \Seen).

RFC822.HEADER

Rfc822Size(u32)

A number expressing the [RFC-2822] size of a message.

RFC822.SIZE

Rfc822Text(NString<'a>)

Equivalent to BODY[TEXT].

RFC822.TEXT

Uid(NonZeroU32)

A number expressing the unique identifier of a message.

UID

Trait Implementations

impl<'a, 'arbitrary: 'a> Arbitrary<'arbitrary> for MessageDataItem<'a>

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

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

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

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 MessageDataItem<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for MessageDataItem<'a>

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

Formats the value using the given formatter.

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

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Hash for MessageDataItem<'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,

impl<'a> IntoBoundedStatic for MessageDataItem<'a>

type Static = MessageDataItem<'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.
