Struct InMemoryTaskStore 

pub struct InMemoryTaskStore { /* private fields */ }

Available on crate features server and a2a-v1 only.

In-memory task store for development and testing.

Uses a RwLock<HashMap> for concurrent access. Not suitable for production deployments that require persistence across restarts.

Implementations

impl InMemoryTaskStore

pub fn new() -> InMemoryTaskStore

Creates a new empty in-memory task store.

Trait Implementations

impl Default for InMemoryTaskStore

fn default() -> InMemoryTaskStore

Returns the “default value” for a type.

impl TaskStore for InMemoryTaskStore

fn create_task<'life0, 'async_trait>( &'life0 self, entry: TaskStoreEntry, ) -> Pin<Box<dyn Future<Output = Result<(), A2aError>> + Send + 'async_trait>>

where 'life0: 'async_trait, InMemoryTaskStore: 'async_trait,

Persists a new task entry.

fn get_task<'life0, 'life1, 'async_trait>( &'life0 self, task_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<TaskStoreEntry, A2aError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, InMemoryTaskStore: 'async_trait,

Retrieves a task by ID.

fn update_status<'life0, 'life1, 'async_trait>( &'life0 self, task_id: &'life1 str, status: TaskStatus, ) -> Pin<Box<dyn Future<Output = Result<(), A2aError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, InMemoryTaskStore: 'async_trait,

Updates the status of an existing task.

fn add_artifact<'life0, 'life1, 'async_trait>( &'life0 self, task_id: &'life1 str, artifact: Artifact, ) -> Pin<Box<dyn Future<Output = Result<(), A2aError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, InMemoryTaskStore: 'async_trait,

where 'life0: 'async_trait, 'life1: 'async_trait, InMemoryTaskStore: 'async_trait,

Finds the most recently updated non-terminal task for a given contextId. Returns None if no non-terminal task exists for the context.
