Struct Part

pub struct Part {
    pub data: Option<Data>,
}

A datatype containing media that is part of a multi-part Content message.

A Part consists of data which has an associated datatype. A Part can only contain one of the accepted types in Part.data.

A Part must have a fixed IANA MIME type identifying the type and subtype of the media if the inline_data field is filled with raw bytes.

Fields

data: Option<Data>

Implementations

impl Part

pub fn text(text: &str) -> Self

Creates a text content part

pub fn to_text(&self) -> &str

Extracts the text in a part

pub fn into_text(self) -> String

Extracts the text in a part and consumes it.

pub fn blob(mime_type: &str, data: Vec<u8>) -> Self

Create a binary blob part

Example

let image = Part::blob("image/png", vec![0u8; 1024]);

pub fn file_data(mime_type: &str, uri: &str) -> Self

Create a file reference part

Trait Implementations

impl Clone for Part

fn clone(&self) -> Part

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Part

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

Formats the value using the given formatter.

impl Default for Part

fn default() -> Self

Returns the “default value” for a type.

impl Display for Part

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

Formats the value using the given formatter.

impl From<&str> for Part

fn from(text: &str) -> Self

Converts to this type from the input type.

impl From<String> for Part

fn from(text: String) -> Self

Converts to this type from the input type.

impl IntoParts for Part

fn into_parts(self) -> Vec<Part>

impl Message for Part

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Part

fn eq(&self, other: &Part) -> 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.
