pub struct Message {
    pub message_id: String,
    pub context_id: Option<String>,
    pub task_id: Option<TaskId>,
    pub role: Role,
    pub parts: Vec<Part>,
    pub metadata: Option<HashMap<String, Value>>,
    pub extensions: Option<Vec<String>>,
    pub reference_task_ids: Option<Vec<TaskId>>,
}

A single message in a conversation between user and agent.

Fields

message_id: String

Unique identifier for the message, generated by the sender.

context_id: Option<String>

Context identifier for grouping related interactions.

task_id: Option<TaskId>

Task identifier this message belongs to.

role: Role

Sender role.

parts: Vec<Part>

Content parts forming the message body.

metadata: Option<HashMap<String, Value>>

Optional metadata for extensions.

extensions: Option<Vec<String>>

Extension URIs relevant to this message.

reference_task_ids: Option<Vec<TaskId>>

Related task IDs for additional context.

Implementations

impl Message

pub fn new(role: Role, parts: Vec<Part>) -> Self

Create a new message with a random ID.

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

Return the text of the first text part, if any.

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Message

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Message

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
