Implementations

impl Session

pub fn new(app_name: impl Into<String>, user_id: impl Into<String>) -> Self

Create a new session.

pub fn export(&self) -> Value

Export session to a JSON-serializable format.

Produces a complete snapshot of the session including metadata, state, and all events. Suitable for backup, migration, or transfer between session service backends.

pub fn import(value: &Value) -> Result<Self, SessionError>

Import a session from an exported JSON value.

Reconstructs a Session from a value previously produced by export. Returns an error if the JSON structure does not match the expected session format.

pub fn rewind_to_invocation(&mut self, invocation_id: &str) -> usize

Rewind the session to a previous invocation state. All events after the given invocation ID are removed. Returns the number of events removed.

impl Clone for Session

fn clone(&self) -> Session

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Session

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Session

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Session

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
