Enum Content 

#[non_exhaustive]
pub enum Content {
    Text {
        text: String,
    },
    Image(Image),
    Document(Document),
    Audio(Audio),
    Video(Video),
    Multi {
        parts: Vec<ContentPrimitive>,
    },
}

Chat input content, mirroring the Python SDK’s Content = str | Image | Document | Audio | Video | list[ContentPrimitive].

This is the top-level union type accepted by crate::agent::AgentHandle::chat(). Unlike ContentPrimitive, it includes the Multi variant for compound multimodal inputs. Scalar variants mirror ContentPrimitive for convenience so callers do not have to wrap a single item in a list.

Use From<&str> or From<String> to create text content ergonomically:

let content: Content = "hello".into();

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Text

Plain text content (backward-compatible with chat("hello")).

Fields

text: String

The text value.

Image(Image)

An image attachment.

Document(Document)

A document attachment.

Audio(Audio)

An audio attachment.

Video(Video)

A video attachment.

Multi

A list of content primitives (multimodal).

Fields

parts: Vec<ContentPrimitive>

The individual content elements.

Implementations

impl Content

pub fn text(s: impl Into<String>) -> Self

Creates a Content::Text variant from any string-like value.

This is a convenience constructor equivalent to Content::Text { text: s.into() }.

Examples

let c = Content::text("hello");
assert!(c.is_text());
assert_eq!(c.as_text(), Some("hello"));

pub const fn is_text(&self) -> bool

Returns true if this content is a Content::Text variant.

Examples

assert!(Content::text("hi").is_text());
assert!(!Content::Image(Image::png(vec![1])).is_text());

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

Returns the text content if this is a Content::Text variant, or None otherwise.

Examples

let text_content = Content::text("hello");
assert_eq!(text_content.as_text(), Some("hello"));

let image_content = Content::Image(Image::png(vec![1]));
assert_eq!(image_content.as_text(), None);

Trait Implementations

impl Clone for Content

fn clone(&self) -> Content

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Content

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

Formats the value using the given formatter.

impl Default for Content

fn default() -> Self

Defaults to an empty Content::Text variant.

Examples

let c = Content::default();
assert_eq!(c.as_text(), Some(""));

impl<'de> Deserialize<'de> for Content

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Content

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

Renders a human-readable summary of the content.

• Text → the text itself.
• Media variants → "[Image: image/png]", etc.
• Multi → "[Multi: 3 parts]".

impl Eq for Content

impl From<&str> for Content

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<Audio> for Content

fn from(audio: Audio) -> Self

Converts to this type from the input type.

impl From<Document> for Content

fn from(doc: Document) -> Self

Converts to this type from the input type.

impl From<Image> for Content

fn from(img: Image) -> Self

Converts to this type from the input type.

impl From<String> for Content

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Vec<ContentPrimitive>> for Content

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

Converts to this type from the input type.

impl From<Video> for Content

fn from(video: Video) -> Self

Converts to this type from the input type.

impl PartialEq for Content

fn eq(&self, other: &Content) -> 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 Content

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
