RunLogWriter

Struct RunLogWriter 

Source
pub struct RunLogWriter { /* private fields */ }
Expand description

Append-only writer shared by the stdout and stderr reader threads of one run. Sequence numbers are capture order across both pipes.

Implementations§

Source§

impl RunLogWriter

Source

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

Opens (creating directories as needed) the run’s output log and resumes sequence numbering after any records already present, so a restarted daemon appends instead of renumbering.

Source

pub fn append( &self, source: OutputSource, stage: Option<&str>, attempt: Option<u32>, stream: OutputStream, bytes: &[u8], ) -> Result<u64>

Appends one chunk and durably flushes it. Capture must be on disk before exit evidence claims it is complete.

Source

pub fn append_at( &self, timestamp_ms: i64, source: OutputSource, stage: Option<&str>, attempt: Option<u32>, stream: OutputStream, bytes: &[u8], ) -> Result<u64>

Appends a chunk with a caller-supplied clock instant. Agent output uses the daemon clock so scheduler deadlines and persisted output agree in tests as well as production.
