pub fn end_debug_span(
log_state: &LogStateRef,
now_ms: f64,
timer: Option<&LogTimer>,
) -> f64Expand description
Closes a span opened by begin_debug_span (TS endDebugSpan), emitting its elapsed-time Debug
entry and returning the elapsed milliseconds. A None timer (debug was disabled when the span
opened) is a no-op returning -1, the “not measured” sentinel.
