Struct TextEventSink 

pub struct TextEventSink { /* private fields */ }

Appends t x y p lines to an open text file — the streaming form of write_text_stream.

Text carries no header at all, so there is nothing to fix up at the end: the file is a valid, readable recording after every append, which makes this the cheapest target for a capture that might be interrupted.

Trait Implementations

impl EventSink for TextEventSink

fn append(&mut self, stream: &EventStream) -> Result<(), IoError>

Appends one window’s events. Empty windows are a no-op. The first non-empty window fixes the sensor size and time base for the whole file.

fn n_events(&self) -> usize

Total events written so far.

fn flush(&mut self) -> Result<(), IoError>

Pushes buffered data at the file without closing it, so a crash mid-recording keeps everything appended so far. Formats that only become readable at finish (npz, rosbag) still flush their bytes, but the file stays incomplete until then.

fn finish(self: Box<Self>) -> Result<(), IoError>

Writes whatever the format keeps for last — an index, a patched header — and closes.
