Struct JsonlSessionStorage 

pub struct JsonlSessionStorage { /* private fields */ }

File-backed storage: holds full state in memory and persists to a JSONL file. Pi-compatible: loads from file on creation, appends on every write.

Implementations

impl JsonlSessionStorage

pub fn create( file_path: PathBuf, cwd: &str, session_id: &str, parent_session_path: Option<String>, ) -> Result<Self, String>

Create a new session at the given path. Writes the header.

pub fn open(file_path: PathBuf) -> Result<Self, String>

Open an existing session file. Loads all entries into memory.

Trait Implementations

impl SessionStorage for JsonlSessionStorage

fn metadata(&self) -> SessionMetadata

Return header-derived metadata.

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

Get the current leaf entry ID (the last non-leaf entry, resolved through leaf entries). Returns None if no entries exist.

fn set_leaf_id(&mut self, leaf_id: Option<&str>) -> Result<(), String>

Persist a leaf entry that records the active session-tree leaf. None means reset to no leaf.

fn create_entry_id(&self) -> String

Generate a unique 8-character hex entry ID, collision-checked.

fn append_entry(&mut self, entry: SessionEntry) -> Result<(), String>

Append a fully-constructed entry. Updates in-memory state and persists to disk.

fn get_entry(&self, id: &str) -> Option<SessionEntry>

Look up an entry by ID.

fn find_entries(&self, type_name: &str) -> Vec<SessionEntry>

Find all entries of the given type string.

fn get_label(&self, id: &str) -> Option<String>

Get the human-readable label for an entry, if any.

fn get_path_to_root( &self, leaf_id: Option<&str>, ) -> Result<Vec<SessionEntry>, String>

Walk from leaf_id (or current leaf, if None) to root, returning entries in path order.

fn get_entries(&self) -> Vec<SessionEntry>

Return all entries in insertion order.

fn path(&self) -> Option<&Path>

The file path on disk, if this storage is file-backed.
