Struct StoredTask 

pub struct StoredTask {
    pub task: A2ATask,
    pub result: Option<A2ATaskResult>,
    pub error: Option<String>,
    pub trace_id: Option<String>,
    pub created_at: Instant,
    pub updated_at: Instant,
}

A task snapshot stored by the server.

Wraps the protocol-visible A2ATask with server-only bookkeeping: the terminal result/error payloads and created_at/updated_at timestamps used for TTL expiry and LRU eviction (P1-2).

Fields

task: A2ATask

The protocol-visible task.

result: Option<A2ATaskResult>

Result of the task (present when the task completed).

error: Option<String>

Error message (present when the task failed).

trace_id: Option<String>

W3C-style trace id carried on the request that created this task (P1-5).

Server-only bookkeeping so a distributed trace can be correlated with a task after creation; the protocol-visible task itself does not expose it.

created_at: Instant

When the task was created.

updated_at: Instant

When the task was last modified.

Implementations

impl StoredTask

pub fn new(task: A2ATask) -> Self

pub fn with_trace_id(self, trace_id: impl Into<String>) -> Self

Attach the trace id that created this task (P1-5).

pub fn touch(&mut self)

Mark the task as modified (bumps updated_at).

pub fn age(&self) -> Duration

Age of this snapshot, measured from its last modification.
