Struct Message 

pub struct Message { /* private fields */ }

A multi-part message, comprising a message body and a list of parts. Messages only contain references to underlying byte buffers and are cheaply cloned.

Implementations

impl Message

pub fn from_body_and_parts(body: Part, parts: Vec<Part>) -> Self

Returns a new message with the given body and parts.

pub fn body(&self) -> &Part

The body of the message.

pub fn parts(&self) -> &[Part]

The list of parts of the message.

pub fn num_parts(&self) -> usize

Returns the total number of parts (excluding the body) in the message.

pub fn len(&self) -> usize

Returns the total size (in bytes) of the message.

pub fn is_empty(&self) -> bool

Returns whether the message is empty. It is always false, since the body is always defined.

pub fn into_inner(self) -> (Part, Vec<Part>)

Convert this message into its constituent components.

pub fn frame_len(&self) -> usize

Returns the total size (in bytes) of the message when it is framed.

pub fn framed(self) -> Frame

Efficiently frames a message containing the body and all of its parts using a simple frame-length encoding:

+--------------------+-------------------+--------------------+-------------------+   ...   +
| body_len (u64 BE)  |   body bytes      | part1_len (u64 BE) |   part1 bytes     |         |
+--------------------+-------------------+--------------------+-------------------+         +
                                                                                     repeat
                                                                                       for
                                                                                     each part

pub fn from_framed(buf: Bytes) -> Result<Self, Error>

Reassembles a message from a framed encoding.

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Message

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Message

fn eq(&self, other: &Message) -> 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 Serialize for Message

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Message
