Struct Task 

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

Task is the core unit of action for A2A. It has a current status and when results are created for the task they are stored in the artifact. If there are multiple turns for a task, these are stored in history.

Fields

id: String

Unique identifier (e.g. UUID) for the task, generated by the server for a new task.

context_id: String

Unique identifier (e.g. UUID) for the contextual collection of interactions (tasks and messages).

status: Option<TaskStatus>

The current status of a Task, including state and a message.

artifacts: Vec<Artifact>

A set of output artifacts for a Task.

history: Vec<Message>

protolint:disable REPEATED_FIELD_NAMES_PLURALIZED The history of interactions from a Task.

metadata: Option<Struct>

protolint:enable REPEATED_FIELD_NAMES_PLURALIZED A key/value object to store custom metadata about a task.

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 Default for Task

fn default() -> Task

Returns the “default value” for a type.

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 From<Task> for Task

fn from(task: Task) -> Self

Converts to this type from the input type.

impl Message for Task

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

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 TryFrom<Task> for Task

type Error = A2aTypeError

The type returned in the event of a conversion error.

fn try_from(inner: Task) -> Result<Self, Self::Error>

Performs the conversion.
