Struct ProfileSession 

pub struct ProfileSession { /* private fields */ }

Streaming profiler session writing JSONL runtime v3 events.

Implementations

impl ProfileSession

pub fn open(path: impl AsRef<Path>, config: ProfileConfig) -> Result<Self>

Open (or truncate) a JSONL profile trace at path.

pub fn phase(&self) -> ExecutionPhase

pub fn step(&self) -> u64

pub fn set_step(&mut self, step: u64)

pub fn begin_operation( &mut self, static_id: impl Into<String>, op: impl Into<String>, inputs: &[String], ) -> Result<String>

Begin timing an operation; returns an event_id for Self::end_operation.

pub fn end_operation( &mut self, event_id: &str, output: Option<String>, ) -> Result<u64>

End a timed operation and emit a runtime v3 operation observation.

pub fn record_edge_timing( &mut self, from_static_id: impl Into<String>, to_static_id: impl Into<String>, duration_ns: u64, ) -> Result<()>

Record average-friendly edge timing between two static tensor/operation ids.

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

pub fn finish(self) -> Result<PathBuf>
