Struct JsonlWriter 

pub struct JsonlWriter<W: Write> { /* private fields */ }

Writes Events as JSONL, assigning sequence numbers.

Each line is flushed as it is written: a subprocess consumer reading the stream live should see a token delta when it happens, not when a buffer happens to fill.

The writer does not police stream structure — emitting Event::RunStarted first and Event::RunFinished last is the caller’s contract.

Implementations

impl<W: Write> JsonlWriter<W>

pub fn new(writer: W) -> Self

pub fn write(&mut self, event: Event) -> Result<u64>

Writes one event and returns the sequence number it was given.

pub fn write_line(&mut self, line: EventLine) -> Result<usize>

Writes one already-numbered line and returns the encoded byte count, including its newline.

pub fn next_seq(&self) -> u64

The sequence number the next write will use.

pub fn into_inner(self) -> W

Returns the underlying writer.
