Enum MessageContent 

pub enum MessageContent {
    Text(String),
    Parts(Vec<ContentPart>),
}

The content of one message: prose, or parts when some of it is not prose.

Variants

Text(String)

Prose, and nothing else. The wire form is a bare string.

Parts(Vec<ContentPart>)

An ordered list of parts, at least one of which is usually not text.

Implementations

impl MessageContent

pub fn as_text(&self) -> Option<&str>

The content as one string, when it is text and nothing else.

None for a parts list — including a parts list that happens to hold only text — because a caller reaching for this wants to know it is seeing the whole message. Use to_text to read what text there is regardless.

pub fn to_text(&self) -> String

Every text part, joined with a newline. Parts carrying bytes or a URI contribute nothing — this is the text, not a description of the message.

pub fn parts(&self) -> impl Iterator<Item = &ContentPart>

The parts, with a text-only content read as a single text part.

pub fn has_media(&self) -> bool

Whether any part carries something a text channel cannot: bytes, or a URI naming them.

What a consumer checks before deciding a message can go somewhere only prose fits — a summarizer, a token estimate, a provider that takes no parts.

Trait Implementations

impl Clone for MessageContent

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageContent

Vec<u8> in a Debug line is one number per byte. A megabyte of PDF in a log is not a diagnostic, so the bytes are reported as a count.

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageContent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MessageContent

impl From<&String> for MessageContent

fn from(text: &String) -> Self

Converts to this type from the input type.

impl From<&str> for MessageContent

fn from(text: &str) -> Self

Converts to this type from the input type.

impl From<ContentPart> for MessageContent

fn from(part: ContentPart) -> Self

Converts to this type from the input type.

impl From<String> for MessageContent

fn from(text: String) -> Self

Converts to this type from the input type.

impl From<Vec<ContentPart>> for MessageContent

fn from(parts: Vec<ContentPart>) -> Self

Converts to this type from the input type.

impl PartialEq for MessageContent

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.

impl Serialize for MessageContent

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
