Enum Part 

pub enum Part {
    Text {
        text: String,
        metadata: Option<Value>,
    },
    File {
        file: FileContent,
        metadata: Option<Value>,
    },
    Data {
        data: Value,
        metadata: Option<Value>,
    },
}

A typed content part within a Message or Artifact.

The A2A spec uses a tagged union ("kind" discriminant) so that clients and agents can safely ignore part types they do not understand. Use Part::text to construct the most common variant without boilerplate.

Examples

use zeph_a2a::{Part};

let text_part = Part::text("Hello!");
assert!(matches!(text_part, Part::Text { .. }));

Variants

Text

Plain or markdown text content.

Fields

text: String

metadata: Option<Value>

File

Binary or URI-referenced file attachment.

Fields

file: FileContent

metadata: Option<Value>

Data

Arbitrary structured JSON data (e.g., tool call results, structured output).

Fields

data: Value

metadata: Option<Value>

Implementations

impl Part

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

Construct a plain-text Part with no metadata.

Examples

use zeph_a2a::Part;

let p = Part::text("Hello, world!");
assert!(matches!(p, Part::Text { ref text, .. } if text == "Hello, world!"));

Trait Implementations

impl Clone for Part

fn clone(&self) -> Part

Returns a duplicate 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<'de> Deserialize<'de> for Part

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for Part

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
