pub struct Compact;
Expand description

Marker for Format that indicates that the compact log format should be used.

The compact format includes fields from all currently entered spans, after the event’s fields. Span fields are ordered (but not grouped) by span, and span names are not shown. A more compact representation of the event’s Level is used, and additional information—such as the event’s target—is disabled by default.
