Struct SessionAdapter 

pub struct SessionAdapter { /* private fields */ }

Read + fork/save adaptor over a Store, implementing SessionSource so the dispatcher can reach the on-disk history. Carries the same Arc<Mutex<ActiveSession>> as SessionSink so /fork atomically swaps the write target.

Trait Implementations

impl Clone for SessionAdapter

fn clone(&self) -> SessionAdapter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionAdapter

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

Formats the value using the given formatter.

impl SessionSource for SessionAdapter

fn current_ulid(&self) -> Option<String>

Ulid of the session currently being recorded into, if any. None when persistence is disabled (--no-persist) — the dispatcher surfaces a clear “persistence disabled” line rather than pretending the save went through.

fn list(&self, limit: u32) -> Result<Vec<SessionSummary>, CmdSessionError>

Newest-first list of up to limit sessions.

fn find(&self, needle: &str) -> Result<SessionSummary, CmdSessionError>

Look up a single session by ulid or a human-assigned label (see Self::save_label). Impls should match ulid first (exact prefix match on at least 6 chars is fine — ulids are time-sortable so a prefix rarely collides) and fall through to label resolution.

fn list_events( &self, ulid: &str, limit: u32, ) -> Result<Vec<ReplayEvent>, CmdSessionError>

All events for a session in seq order (oldest first), up to limit. Mirrors zero_session::Store::list_events’s semantics but returns this crate’s ReplayEvent.

fn save_label(&self, ulid: &str, label: &str) -> Result<(), CmdSessionError>

Associate a short human label with a session ulid. Labels are stored as milestones (session.label.<label> → <ulid>) so they survive CLI restarts and are queryable without schema changes. Overwriting a label is fine — the old one is silently reassigned.

fn fork_from_current(&self) -> Result<Option<String>, CmdSessionError>

Start a new session whose parent_ulid is the current one. The impl becomes the authority for the new session’s ulid; returns it so the dispatcher can echo the fork line. None is returned when persistence is disabled.
