Struct SpanStartEvent 

pub struct SpanStartEvent {
    pub id: String,
    pub parent_id: Option<String>,
    pub name: String,
    pub start_ns: u64,
    pub kind: SpanKind,
    pub measured: bool,
    pub step: Option<ExecutionStep>,
}

Opens a span in the profiler hierarchy.

Fields

id: String

parent_id: Option<String>

name: String

start_ns: u64

Monotonic timestamp in nanoseconds since the profile run started.

kind: SpanKind

Span classification (function / op / module). Serialized as span_kind because the JSONL event discriminator also uses the key kind.

measured: bool

step: Option<ExecutionStep>

PyTorch-style training step (forward / backward / optimizer) for memory categories.
