Enum Part 

pub enum Part {
    Text(TextPart),
    File(FilePart),
    Data(DataPart),
}

A unit of content within a Message.

The wire form is the proto’s oneof content: the JSON object has exactly one of text, file, or data as a top-level field. The optional metadata field rides alongside whichever content field is present.

Examples

use protocol_droid::domain::a2a::message::{Message, MessageRole, Part, TextPart};

let message = Message::new(MessageRole::User)
    .with_part(Part::Text(TextPart {
        text: "Hello, agent.".to_owned(),
        metadata: std::collections::BTreeMap::new(),
    }));
let json = serde_json::to_string(&message).unwrap();
assert!(json.contains(r#""role":"user""#));
assert!(json.contains(r#""text":"Hello, agent.""#));

Variants

Text(TextPart)

A UTF-8 string. Wire form: { "text": "..." }.

File(FilePart)

A file (named, MIME-typed, with either an inline base64 payload or a URI). Wire form: { "file": {...} }.

Data(DataPart)

A structured JSON value. Wire form: { "data": {...} }.
