Struct SpanTrace 

pub struct SpanTrace { /* private fields */ }

Captured obs::scope! ancestry. Like tracing-error::SpanTrace.

Implementations

impl SpanTrace

pub fn capture() -> SpanTrace

Walk the active task’s obs::scope! stack and capture frames outermost-first. Cheap: zero allocation when the stack is empty, linear in stack depth otherwise.

pub fn is_empty(&self) -> bool

true when no scope was active at capture time.

pub fn len(&self) -> usize

Number of captured frames.
