Struct SessionManager 

pub struct SessionManager {
    pub log: SessionLog,
    pub history: Vec<ChatMessage>,
}

Manages the storage and retrieval of session logs.

Creates the log file that the current run writes to, and loads the transcript of the session being resumed, if any.

Fields

log: SessionLog

The session log this run writes to (null when no session-logs directory was given).

history: Vec<ChatMessage>

Transcript of the session being resumed; empty when starting fresh.

Implementations

impl SessionManager

pub fn new(session_logs: Option<&Path>, resume: &Resume) -> Result<Self>

Create the session log for this run and, if requested, load the transcript of the session to resume.

The resume target is resolved before the new log file is created, so the file created by this call can never be picked as the newest log.

A Resume::File whose path is a bare file name (no directory part) and not found in the current directory is looked up in the session-logs directory, if one was given, also trying <name>.jsonl when the name has no extension.

fn newest_log(dir: &Path) -> Result<PathBuf>

Find the newest non-empty session log in dir, by modification time (ties broken by name, which is timestamped).

fn resolve_resume_file( file: &Path, session_logs: Option<&Path>, ) -> Result<PathBuf>

Resolve the file to resume from.

A bare file name (no directory part, i.e. no slash) that does not exist in the current directory is looked up in the session-logs directory, if one was given, also trying <name>.jsonl when the name has no extension. Anything else is used as-is: a path that exists nowhere then fails with the natural load error, unless a directory was given and the bare name is in neither place, which is its own error.

fn is_bare_name(file: &Path) -> bool

A bare file name: exactly one path component, so no directory part (no slash).

fn new_log_name() -> String

A session log file name, timestamped so that names sort chronologically.

Trait Implementations

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

Formats the value using the given formatter.
