Struct Task 

pub struct Task {
    pub id: TaskId,
    pub context_id: ContextId,
    pub status: TaskStatus,
    pub history: Option<Vec<Message>>,
    pub artifacts: Option<Vec<Artifact>>,
    pub metadata: Option<Value>,
}

A unit of work managed by an A2A agent.

The wire kind field ("task") is injected by enclosing discriminated unions such as crate::events::StreamResponse and crate::responses::SendMessageResponse. Standalone Task values received over the wire may include kind; serde silently tolerates unknown fields, so no action is needed on the receiving side.

Fields

id: TaskId

Unique task identifier.

context_id: ContextId

Conversation context this task belongs to.

status: TaskStatus

Current status of the task.

history: Option<Vec<Message>>

Historical messages exchanged during this task.

artifacts: Option<Vec<Artifact>>

Artifacts produced by this task.

metadata: Option<Value>

Arbitrary metadata.

Trait Implementations

impl Clone for Task

fn clone(&self) -> Task

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Task

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Task

fn deserialize<__D>( __deserializer: __D, ) -> Result<Task, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Task

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Task

impl StructuralPartialEq for Task
