Implementations

impl Session

pub fn new( model: &str, thinking_level: &str, system_prompt: Option<&str>, ) -> Self

pub fn new_from_compaction(parent: &Session, summary: String) -> Self

Create a new session from a compaction summary, linked to the parent.

pub fn auto_title(&mut self)

Set title from the first user message if not already set

pub async fn save(&self) -> Result<()>

pub fn load(id: &str) -> Result<Self>

pub fn info(&self) -> SessionInfo

pub fn set_name(&mut self, name: &str) -> Result<()>

Assign a name to this session. Validates name, enforces uniqueness across sessions, and rejects collisions with existing chain names. Idempotent: re-applying the current name is a no-op.

pub fn clear_name(&mut self)

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.

where __S: Serializer,

Serialize this value into the given Serde serializer.
