Struct SessionWriter 

pub struct SessionWriter { /* private fields */ }

Append-only JSONL writer with crash-safe flush.

Implementations

impl SessionWriter

pub fn create(path: &Path, header: SessionHeader) -> Result<Self>

Create a new session file with the given header.

pub fn open(path: &Path) -> Result<Self>

Open an existing session file for appending (seeks to end).

If the file’s last line is incomplete (no trailing newline from a crashed write), the incomplete tail is truncated so subsequent appends land on a clean line boundary.

pub fn append(&mut self, entry: &SessionEntry) -> Result<()>

Append a session entry as a new JSONL line.
