Struct SpanTrace

pub struct SpanTrace(/* private fields */);

Methods from Deref<Target = SpanTrace>

pub fn with_spans( &self, f: impl FnMut(&'static Metadata<'static>, &str) -> bool, )

Apply a function to all captured spans in the trace until it returns false.

This will call the provided function with a reference to the Metadata and a formatted representation of the fields of each span captured in the trace, starting with the span that was current when the trace was captured. The function may return true or false to indicate whether to continue iterating over spans; if it returns false, no additional spans will be visited.

pub fn status(&self) -> SpanTraceStatus

Returns the status of this SpanTrace.

The status indicates one of the following:

• the current subscriber does not support capturing SpanTraces
• there was no current span, so a trace was not captured
• a span trace was successfully captured
