Struct InvocationContext 

pub struct InvocationContext { /* private fields */ }

Implementations

impl InvocationContext

pub fn new_typed( invocation_id: String, agent: Arc<dyn Agent>, user_id: UserId, app_name: AppName, session_id: SessionId, user_content: Content, session: Arc<dyn AdkSession>, ) -> Result<Self>

Create a new invocation context from validated typed identifiers.

pub fn new( invocation_id: String, agent: Arc<dyn Agent>, user_id: String, app_name: String, session_id: String, user_content: Content, session: Arc<dyn AdkSession>, ) -> Result<Self>

pub fn with_mutable_session_typed( invocation_id: String, agent: Arc<dyn Agent>, user_id: UserId, app_name: AppName, session_id: SessionId, user_content: Content, session: Arc<MutableSession>, ) -> Result<Self>

Create an invocation context that reuses an existing mutable session and validated typed identifiers.

pub fn with_mutable_session( invocation_id: String, agent: Arc<dyn Agent>, user_id: String, app_name: String, session_id: String, user_content: Content, session: Arc<MutableSession>, ) -> Result<Self>

Create an InvocationContext with an existing MutableSession. This allows sharing the same mutable session across multiple contexts (e.g., for agent transfers).

pub fn with_branch(self, branch: String) -> Self

pub fn with_artifacts(self, artifacts: Arc<dyn Artifacts>) -> Self

pub fn with_memory(self, memory: Arc<dyn Memory>) -> Self

pub fn with_run_config(self, config: RunConfig) -> Self

pub fn with_request_context(self, ctx: RequestContext) -> Self

Set the request context from the server’s auth middleware bridge.

When set, user_id() returns request_context.user_id (overriding the session-scoped identity), and user_scopes() returns request_context.scopes. This is the explicit authenticated user override — RequestContext remains separate from ExecutionIdentity and AdkIdentity (it does not carry session or invocation IDs).

pub fn with_shared_state(self, shared: Arc<SharedState>) -> Self

Set the shared state for parallel agent coordination.

pub fn mutable_session(&self) -> &Arc<MutableSession>

Get a reference to the mutable session. This allows the Runner to apply state deltas when events are processed.

Trait Implementations

impl CallbackContext for InvocationContext

fn artifacts(&self) -> Option<Arc<dyn Artifacts>>

fn shared_state(&self) -> Option<Arc<SharedState>>

Returns the shared state for parallel agent coordination. Returns None when not running inside a ParallelAgent with shared state enabled.

fn tool_outcome(&self) -> Option<ToolOutcome>

Returns structured metadata about the most recent tool execution. Available in after-tool callbacks and plugin hooks. Returns None when not in a tool execution context.

fn tool_name(&self) -> Option<&str>

Returns the name of the tool about to be executed. Available in before-tool and after-tool callback contexts.

fn tool_input(&self) -> Option<&Value>

Returns the input arguments for the tool about to be executed. Available in before-tool and after-tool callback contexts.

impl InvocationContext for InvocationContext

fn agent(&self) -> Arc<dyn Agent>

fn memory(&self) -> Option<Arc<dyn Memory>>

fn session(&self) -> &dyn Session

fn run_config(&self) -> &RunConfig

fn end_invocation(&self)

fn ended(&self) -> bool

fn user_scopes(&self) -> Vec<String>

Returns the scopes granted to the current user for this invocation.

fn request_metadata(&self) -> HashMap<String, Value>

Returns the request metadata from the auth middleware bridge, if present.

impl ReadonlyContext for InvocationContext

fn invocation_id(&self) -> &str

fn agent_name(&self) -> &str

fn user_id(&self) -> &str

fn app_name(&self) -> &str

fn session_id(&self) -> &str

fn branch(&self) -> &str

fn user_content(&self) -> &Content

fn try_app_name(&self) -> Result<AppName, AdkError>

Returns the application name as a typed AppName.

fn try_user_id(&self) -> Result<UserId, AdkError>

Returns the user identifier as a typed UserId.

fn try_session_id(&self) -> Result<SessionId, AdkError>

Returns the session identifier as a typed SessionId.

fn try_invocation_id(&self) -> Result<InvocationId, AdkError>

Returns the invocation identifier as a typed InvocationId.

fn try_identity(&self) -> Result<AdkIdentity, AdkError>

Returns the stable session-scoped AdkIdentity triple.

fn try_execution_identity(&self) -> Result<ExecutionIdentity, AdkError>

Returns the full per-invocation ExecutionIdentity.
