Struct TaskStore 

pub struct TaskStore { /* private fields */ }

Available on crate feature server only.

In-memory storage for finished A2A tasks.

Each record carries the authenticated user that started the task, or None when no authentication was configured. Owner-scoped reads (get_for) only return a record to the same principal. Records are evicted according to the store’s A2aTaskRetention.

Implementations

impl TaskStore

pub fn new() -> TaskStore

Creates a store with the default A2aTaskRetention.

pub fn with_retention(retention: A2aTaskRetention) -> TaskStore

Creates a store that evicts records according to retention.

pub async fn store(&self, task: Task)

Stores task without an owner.

An ownerless record is visible only to unauthenticated callers. Use store_for to record the principal that started it.

pub async fn store_for(&self, owner: Option<&str>, task: Task)

Stores task as owned by owner, then applies the retention policy.

pub async fn get(&self, task_id: &str) -> Option<Task>

Returns a stored task regardless of its owner.

This is for programmatic access by the server operator; request handlers use get_for.

pub async fn get_for(&self, owner: Option<&str>, task_id: &str) -> Option<Task>

Returns a stored task only when it belongs to owner.

A task owned by someone else is reported exactly like a missing one, so the response does not disclose that the ID exists.

pub async fn remove(&self, task_id: &str) -> Option<Task>

Removes a stored task regardless of its owner.

pub async fn len(&self) -> usize

Returns the number of records held, including expired ones not yet evicted.

pub async fn is_empty(&self) -> bool

Returns true when the store holds no records.

Trait Implementations

impl Default for TaskStore

fn default() -> TaskStore

Returns the “default value” for a type.
