pub struct ErrorSubscriber<C, F = DefaultFields> { /* private fields */ }
Expand description
A subscriber that enables capturing SpanTrace
s.
Optionally, this type may be constructed with a field formatter to use when formatting the fields of each span in a trace. When no formatter is provided, the default format is used instead.
