Struct Task 

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

A2A Task (proto message Task) — returned by SendMessage / GetTask / CancelTask. Fields beyond the spec-required id/status are optional and tolerate absence: a peer that omits contextId or artifacts still parses.

Fields

id: String

Spec-REQUIRED: no #[serde(default)] — a Task without id is rejected at deserialization (proto field_behavior = REQUIRED). An empty id ("") is also rejected.

context_id: String

status: TaskStatus

Spec-REQUIRED: no #[serde(default)] — a Task without status is rejected at deserialization.

artifacts: Vec<Artifact>

history: Vec<Message>

metadata: Option<Value>

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

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<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Task

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Task

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for Task

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
