Trait representing a conversation session with state and event history.

Required Methods

fn id(&self) -> &str

Returns the session identifier.

fn app_name(&self) -> &str

Returns the application name that owns this session.

fn user_id(&self) -> &str

Returns the user identifier for the session owner.

fn state(&self) -> &dyn State

Returns a reference to the session’s state store.

fn events(&self) -> &dyn Events

Returns a reference to the session’s event history.

fn last_update_time(&self) -> DateTime<Utc>

Returns the timestamp of the last update to this session.

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 AdkError::config 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 AdkError::config 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 id(). Returns an error if the raw string fails validation.

Errors

Returns AdkError::config 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.

Dyn Compatibility

This trait is dyn compatible.

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