pub struct Compact;
Available on crate features
fmt
and std
only.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) 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 (but can be enabled explicitly).
