Struct TraceWriter 

pub struct TraceWriter { /* private fields */ }

Appends records to a trace file. Not Sync; a profiler must serialize writes (the profiler’s sink mutex does this).

Implementations

impl TraceWriter

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

Create (truncate) a trace file and write the header.

pub fn write(&mut self, record: &TraceRecord) -> Result<()>

Append one record.

pub fn write_event(&mut self, event: &TraceEvent) -> Result<()>

Append one event.

pub fn count(&self) -> u64

Number of records written.

pub fn flush_buffered(&mut self) -> Result<()>

Flush buffered bytes to the file without finishing the session.

pub fn finish(&mut self, summary: &TraceSummary) -> Result<()>

Write the session summary and flush. The file is left open for inspection; call close to release it.

pub fn close(self) -> Result<()>

Close the file (flush and drop).
