Read-only access to invocation metadata.

Provides identity information (user, app, session, invocation) and the current user content. Implemented by all context types.

Required Methods

fn invocation_id(&self) -> &str

Returns the current invocation identifier.

fn agent_name(&self) -> &str

Returns the name of the currently executing agent.

fn user_id(&self) -> &str

Returns the user identifier for this session.

fn app_name(&self) -> &str

Returns the application name for this session.

fn session_id(&self) -> &str

Returns the session identifier.

fn branch(&self) -> &str

Returns the current conversation branch.

fn user_content(&self) -> &Content

Returns the user’s input content for this invocation.

Provided Methods

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

Returns the application name as a typed AppName.

Parses the value returned by app_name(). Returns an error if the raw string fails validation (empty, null bytes, or exceeds the maximum length).

Errors

Returns an error when the underlying string is not a valid identifier.

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

Returns the user identifier as a typed UserId.

Parses the value returned by user_id(). Returns an error if the raw string fails validation.

Errors

Returns an error when the underlying string is not a valid identifier.

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

Returns the session identifier as a typed SessionId.

Parses the value returned by session_id(). Returns an error if the raw string fails validation.

Errors

Returns an error when the underlying string is not a valid identifier.

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

Returns the invocation identifier as a typed InvocationId.

Parses the value returned by invocation_id(). Returns an error if the raw string fails validation.

Errors

Returns an error when the underlying string is not a valid identifier.

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

Returns the stable session-scoped AdkIdentity triple.

Combines try_app_name(), try_user_id(), and try_session_id() into a single composite identity value.

Errors

Returns an error if any of the three constituent identifiers fail validation.

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

Returns the full per-invocation ExecutionIdentity.

Combines try_identity() with the invocation, branch, and agent name from this context.

Errors

Returns an error if any of the four typed identifiers fail validation.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
